Synthesis and applications of 1,1-diborylated cyclopropanes: Facile route to 1,2-diboryl-3-methylenecyclopentenes

Cyclopropylidene lithium carbenoids reacted with bis-(pinacolato)diboron in THF/Et2O at -110C to give various 1,1-diborylated cyclopropanes in good yields. Treatment of the diborylated cyclopropanes with 3-chloro-1-lithio-3-methyl-1-butyne produced the corresponding diborylated allenylcyclopropanes, which underwent ring-expansion in the presence of a Rh catalyst to give 1,2-diborylated methylenecyclopentenes conveniently.

Pd-catalyzed reduction of aldehydes to alcohols using formic acid as the hydrogen donor

Facile and selective reduction of aromatic aldehydes as well as aliphatic aldehydes to alcohols was achieved using formic acid as the hydrogen donor in the presence of a catalytic amount of Pd(OAc)2 and Cy3P. It was found that both hydrogen atoms in the formic acid molecule can serve as the hydride source. [Supplementary materials are available for this article.

Palladium-catalyzed aerobic oxidative carbonylation of arylboronate esters under mild conditions

(Figure Presented) “CO”n Air: The title reaction was carried out using [PdCl2(PPh3)2 ] as the catalyst precursor under very mild conditions (balloon pressure of CO and air, at 40- 50C), and produced a wide range of aryl carboxyl esters 2 in good to excellent yields. Remarkable selectivity between oxidative carbonylation and homocoupling of arylboronate esters l was also achieved.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of 1,1′-Bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex, you can also check out more blogs about95464-05-4

The role of reversible oxidative addition in selective palladium(0)- catalyzed intramolecular cross-couplings of polyhalogenated substrates: Synthesis of brominated indoles

A Pd(0)-catalyzed C-N bond-forming reaction leading to the synthesis of brominated indoles is described. The use of the phosphine ligand PtBu 3 is necessary for reactivity. It is proposed that the bulky ligand serves to prevent inhibition of the catalyst by facilitating reversible oxidative addition into the product C-Br bond. Intramolecular coupling of a vinyl bromide in the presence of an aryl iodide can take place, demonstrating unprecedented levels of selectivity.

A diaryl-linked [Pd2L4]4+ metallosupramolecular architecture: Synthesis, structures and cisplatin binding studies

A diaryl-linked tripyridyl ligand (L), 2,6-bis[4-(3-pyridinyl)phenyl]-4-(hydroxymethyl)pyridine, was synthesised in good yield (57%) exploiting the Pd-catalysed Suzuki cross-coupling method and used to assemble a new [Pd2L4]4+ metallosupramolecular cage architecture. These systems have been characterised by NMR, IR and UV-vis spectroscopies, mass spectrometry, elemental analysis and by X-ray crystallography. It was shown using NMR spectroscopy and X-ray crystallography that the cage acts as a host for anions. However, efforts to bind the anticancer drug cisplatin within the central cavity of the cage were unsuccessful. This appears to be connected to steric effects caused by the aryl spacer units of the ligands forming the cage.

Palladium-catalyzed controlled carbopalladation of benzyne

2-Trimethylsilylphenyl trifluoromethanesulfonate 1a, a benzyne precursor, reacted with the allylic chlorides 2a – f in the presence of CsF (2.0 equiv) and Pd2(dba)3¡¤CHCl3 (2.5 mol %)-dppf (5 mol %) in a 1:1 mixed solvent of CH3CN and THF to produce the phenanthrene derivatives 3 along with their minor regioisomers 4 in good yields (i) and the reaction of 1a with 2a and the internal alkynes 15a,c – e afforded the naphthalene derivatives 16 in moderate yields (ii). The reaction of benzyne precursor 1a with the alkynes 15a – c,f – h in the presence of Pd(OAc)2 (5 mol %)-(o-tolyl)3P (5 mol %) catalyst and CsF (2.0 equiv) in CH3CN gave the phenanthrene derivatives 17 (iii), whereas the reaction of 1a with the alkynes 15a,b,i in the presence of the same catalysts and CsF in CH3CN – toluene gave the indene derivatives 18 in good yields (iv). Detailed mechanistic investigation revealed that the former two reactions i and ii proceed through carbopalladation to free benzyne, while the latter two reactions iii and iv proceed through the nonfree benzyne mechanism, in which the initial step of the catalytic cycle begins with Pd(0) insertion to the Ar – OTf bond of 1.
