Insertion of Pt into C-H and C-S bonds of thiophene derivatives. The X-ray crystal structure of a thiaplatinacycle of 3,6-dimethylthieno [3,2-b]thiophene

Treatment of the zerovalent platinum complex [Pt(PEt3) 4] with 3,6-dimethylthieno[3,2-b]thiophene leads to a six-membered, approximately planar thiaplatinacycle, which has been characterised spectroscopically and by a single crystal X-ray determination. The reaction of [Pt(PEt3)4] with 2,2?-bithiophene and 1-methyl-2-(2-thienyl)pyrrole produced two types of products, thiaplatinacycles resulting from C-S insertion and platinum(II) hydrides arising from C-H insertion. These complexes were characterised spectroscopically.

Regioselective Synthesis of 1,2-Benzothiazine 1,1-Dioxide Derivatives by Intramolecular Heck Cyclization

An efficient method for the synthesis of bioactive heterocycles containing 1,2-benzothiazine 1,1-dioxide derivatives via Pd-catalyzed intramolecular Heck cyclization is reported. The method offers the regioselective synthesis of highly functionalized benzosultams in 80-85% yields. The structure of benzosultam derivatives is confirmed from single crystal X-ray diffraction.

Increasing thiophene spacers between thieno[3,2-b]thiophene and benzothiadiazole units in backbone to enhance photovoltaic performance for their 2-D polymers

In order to investigate the effect of thiophene spacers in backbone between electron-rich thieno[3,2-b]thiophene (TT) and electron-deficient benzothiadiazole (BT) units on the photovoltaic properties, novel two-dimensional (2-D) polymers with appending conjugated dioctylthiophene units in the 3,6-positions of TT were designed and synthesized, in which one or two thiophene spacers were embedded between TT and BT, respectively. The polymer with two thiophene spacers exhibited a broader absorption and higher power conversion efficiency in the bulk hetero-junction polymer solar cells. The best performance with efficiency up to 3.34% and short-circuit current values of 12.6 mA/cm2 was obtained, which are 2.1 and 3.0 times higher than those corresponding values for the polymer with only one thiophene spacer. Our work indicates that increasing the numbers of thiophene spacers between TT and BT moieties in the backbone is an efficient method to enhance the photovoltaic performance of their 2-D polymers in polymer solar cells.

On the formation of Pd(II) complexes of Trost modular ligand involving N-H activation or P,O coordination in Pd-catalyzed allylic alkylations

Specific chiral ligands have been designed by Trost et al. to perform enantioselective Pd-catalyzed allylic alkylations. It is shown that the Pd(0) complex formed by addition of the Trost ligand (4) to Pd0(dba)2 is not stable in most solvents (acetone, DMF, CH2Cl2). Indeed, Pd0(dba)(4) leads to the formation of a stable PdII complex 5 (X-ray structure), likely by activation of the two N-H bonds of the ligand by the Pd0 centre. The formation of the PdII complex competes with the reaction of Pd0(4) with (E)-PhCH{double bond, long}CH-CH(OAc)-Ph, excluding any investigation of the kinetics of the latter reaction. The ionization steps from intermediate (eta2-PhCH{double bond, long}CH-CH(OAc)-Ph)Pd0(4) were found to be very slow. The cationic P,P complex [(eta3-Ph-CH-CH-CH-Ph)Pd(4)]+, expected to be generated by addition of 2 equiv. of 4 to the precursor [(eta3-Ph-CH-CH-CH-Ph)Pd(mu-Cl)]2, in the presence of a chloride scavenger, leads to a complex mixture whereas addition of 1 equiv. of 4 affords a stable bis-cationic PdII complex {[(eta3-Ph-CH-CH-CH-Ph)Pd]2(4)]}2+, 2 (BF4-) (X-ray structure) via a P,O complexation of each allyl-Pd moieties. This dissymmetric P,O coordination will favour the enantioselectivity of Pd-catalyzed allylic alkylation of (E)-PhCH{double bond, long}CH-CH(OAc)-Ph by the control of the regioselectivity of the nucleophilic attack onto the allylic ligand which is responsible of the enantioselectivity of the overall catalytic reaction.

Synthesis, X-ray, spectroscopic and a preliminary Suzuki coupling screening studies of a complete series of dppfMX2 (M=Pt, Pd; X=Cl, Br, I)

A complete series of dppfMX2 (M=Pt, Pd; X=Cl, Br, I) compounds have been synthesized using different routes, and characterized fully. The synthesis of dppfPdI2 has been achieved by reacting Pd(COD)Cl2 with dppf in the presence of NaI. X-ray structures of dppfPdBr2 and dppfPdI2 have also been reported for the first time in this study. A preliminary Suzuki coupling screening study reveals that dppfPdX2 compounds are superior to the conventional Ph3P-based catalysts and bidentate phosphine-based ligands. Reactions carried out under in situ conditions also gave a similar trend, but their respective activities were much lower than that of the fully formed catalysts.
