Palladium(II) complexes of aromatic hemiporphyrazines were prepared by the reaction of bis(dibenzylideneacetone)palladium(0) with the corresponding metal-free macrocycles. Single crystal X-ray analysis revealed that a palladium(II) ion was coordinated inside the macrocyclic cavity to form two Pd-C bonds. Electronic properties of the metalloorganic compounds were characterized by NMR, UV-vis-NIR, and magnetic circular dichroism (MCD) spectroscopy.

We have studied the possible reaction pathways operating in the Pd-catalyzed remote C-H functionalization of N-(2-haloaryl)acrylamides from an organometallic approach. We have isolated and characterized several proposed reaction intermediates, such as sigma-alkyl-Pd complexes and spiro C,C-palladacycles, and evaluated the role of the base and the auxiliary ligands coordinated to Pd in the remote C-H activation process. In addition, the reactivity of these intermediates toward different unsaturated species such as benzyne, alkynes, and isocyanides has been studied in order to gain further insight into the reaction mechanism leading to functionalized spiro-oxoindoles.

A palladium-catalyzed domino transformation of gem-dibromoolefins leading to novel polycyclic benzo[c]carbazoles is described. A unique feature of the current reaction is the participation of both bromides in C-H functionalization processes. Mechanistic studies were conducted to ascertain the sequence of reaction events, and the results indicate that the (Z)-bromide likely reacts in preference to the (E)-bromide.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

The oxidative addition of 2,4,6-tribromo-1,3,5-benzenetricarboxaldehyde (C6(CHO)3Br3) to 1, 2, or 3 equiv of [Pd(dba)2] ([Pd2(dba)3]?dba) and N^N affords, respectively, the mono-, di-, or trinuclear complexes [Pd{C 6(CHO)3Br2}Br(N^N)] (N^N = tmeda = N, N,N’,N”-tetramethylethylenediamine (la), tbbpy = 4,4′-di-tert-butyl-2,2′- bipyridine (1b), bpy = 2,2′-bipyridine, (1c)); [{PdBr(N^N)}2{mu 2C6(CHO)3Br)] (N^N = tmeda (2a), tbbpy (2b)); or [{PdBr(N^N)}3{mu3-C6(CHO)3}] (N^N = tmeda (3a), tbbpy (3b)). The reactions of C6(CHO) 3Br3 with a mixture of [Pd(dba)2] and PR 3 lead, depending on the nature of the phosphine and the molar ratio of the reagents, to the mononuclear trans-[Pd{C6(CHO) 3Br2}Br(PR3)2] (R = Ph (1d), R 3 = Me2Ph (1e)) or the dinuclear [{trans-PdBr(PMe 2Ph)2}2{mu2C6(CHO) 3Br}] (2e) complex. All attempts to prepare trinuclear phosphine complexes using this method of synthesis have been unsuccessful. However, displacement of the tbbpy ligand in 3b by an excess of PMe3 affords the trinuclear complex [{trans-PdBr(PMe3)2} 3{mu3-C6(CHO)3}] (3f). The crystal structures of 1b, 1d, 2a- CDCl3, and 2e have been determined by X-ray diffraction studies.

The electron donor-acceptor based hybrid ternary nanostructures remains a frontier area of research in designing novel light harvesting devices. Here we report the morphological and photophysical study in Intra-triad and Inter-triad nanoparticles by using electron donating donor-acceptor-donor (D-A-D) type Diketopyrrolopyrrole (DPP) molecule which imparts the advantages of both polymers and small molecules and non fullerene electron acceptor, Naphthalene diimide (NDI) and fullerene based acceptor, Phenyl-C61-butyric acid methyl ester (PCBM). Both these nanostructures were fabricated by modified mini-emulsion technique. The Intra-triad nanostructure contains DPP, NDI and PCBM molecules inside the same matrix and in case of Inter-triad nanostructure, individual nanoparticles are attached together by electrostatic force. The morphological optimizations in hybrid nanostructures are performed with the help of AFM studies. We have further studied the structure mediated charge transfer phenomena and lifetime decay profiles by time resolved photoluminescence and steady state spectroscopy measurements. Due to the favorable energy levels, DPP molecules have been employed here as donor molecule for cascade energy transfer in ternary heterotriad geometric system.

Due to the favorable energy levels, DPP molecules have been employed here as donor molecule for cascade energy transfer in ternary heterotriad geometric system. The steady state and time resolved spectroscopy reveal interesting photophysics about the ternary heterostructures. The Intra-triad system has shown improved charge transfer properties compared to Inter-triad system and could be a futuristic material for opto-electronic applications.

The (E)- and (Z)-styryl isomers of trans-[Pd(CH=CHPh)Br(PMePh 2)2](1a) and [Pd(n2-PhCH= CHPMePh2) Br(PMePh2)] (2a) were prepared, and their C-P reductive elimination (1a – 2a) and C-P oxidative addition (2a – 1a) behaviors examined. Kinetics and thermodynamics of the reactions are strongly affected by E/Z configurations of the styryl group and solvent polarity. Complex (E)-1a readily undergoes C- P reductive elimination in CD2Cl2 as a polar solvent in high selectivity. On the other hand, while the (Z)-isomer of 1a is unreactive toward reductive elimination, (Z)-2a undergoes C-P oxidative addition favorably in nonpolar benzene. X-ray diffraction analysis and DFT calculations for 1a and 2a provided reasonable accounts for these reaction features. Kinetic examinations revealed two types of C- P reductive elimination processes, which involve predissociation and association of the PMePh2 ligand, respectively.
