Methods for the direct synthesis of difluoromethylated arenes are sparse, despite the importance of the difluoromethyl group in medical, agro-, and materials chemistry. A palladium-catalyzed decarbonylative cross-coupling reaction of acid chlorides with a difluoromethyl zinc reagent is achieved to access difluoromethylated compounds. The transformation proceeds at room temperature and shows broad functional group tolerance, thus providing a general and efficient method for decarbonylative difluoromethylation of a wide range of aromatic carboxylic acids.

This review gives an overview of the progress on tri- and high-nuclearity palladium(II) platinum(II) complexes and discusses recent developments in the chemistry of these complexes. Three or more square-planar metal atoms can be assembled in several ways resulting into myriad geometric forms of the resulting complexes. These square planes may be sharing a corner, an edge and two edges or even separated by ligands having their donor atoms incapable of forming chelates yielding dendrimers and self-assembled molecules. A variety of ligands have been used to stabilize these complexes. The chemistry of these complexes has been dealt based on nuclearity of the complexes. Synthetic, spectroscopic, structural aspects and applications of these complexes are described in this review.

The crystal and molecular structures of the hexarhodium carbonyl clusters Rh6(CO)15L (L = P(OPh)3, 1; P(4-XC6H4)3, (X = CF3, 2; Cl, 3; F, 4; OMe, 5); P(nBu)3, 6; Me2SO, 7; MeCN, 8; C8H14, 9) have been determined by single crystal X-ray crystallography. Redetermination of the structure of the parent Rh6(CO)16 cluster, 10, has also been performed and all the results are compared with those for the rather disparate group of monosubstituted derivatives reported earlier. The structures all relate closely to that of the parent which has an octahedral array of Rh atoms with four opposite faces triply bridged by CO ligands. Each Rh atom also has two terminal CO groups attached. The substituents simply replace one of the terminal COs. A group of ligands, comprised of the P-donors and cyclooctene, all show distortions with a high degree of stereoselectivity in the vicinity of the substitution site, and demonstrate the significantly local character of the effect. The effects on the terminal CO groups are mainly limited to the CO attached to the substituted Rh atom for which there is a clear decrease in the Rh-CO distance and a smaller lengthening of the C-O distance. The triangle of Rh atoms that contains the substituted Rh atom, with the substituent projecting above that triangle, shows a pronounced lengthening of the Rh-Rh bonds cis to the heteroligand. There is an equally pronounced shortening of the Rh-Rh bond across the triangle from the substituted Rh atom. A third effect is the displacement of the CO groups in triply bridged Rh3 triangles containing the RhL moiety, so that they almost doubly bridge the two Rh-Rh bonds cis to the substituted Rh atom. Although no clear correlations exist within this group of substituents the localized effects can generally be associated with an increase of electron density on the substituted Rh atom. The other monosubstituted clusters that contain quite different neutral and anionic heteroligands do not display common trends in the structural distortions induced by the substituents, and this is evidently due to the very varied nature of the ligands within this group.

RhH(PPh3)4 and 1,2-bis(diphenylphosphino)benzene (dppBz) catalyzed the oxidative coupling reaction of aryl benzyl ketones giving 2,3-diaryl-1,4-diketones in high yields. 3,3-Dimethyl-1-methylthio-2-butanone was used as the oxidizing reagent, which was converted to 3,3-dimethyl-2- butanone and dimethyl disulfide. Rhodium enolates were catalytically formed from ketones, which underwent oxidative coupling using an organosulfur reagent.

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.Recommanded Product: 1,2-Bis(diphenylphosphino)benzene, you can also check out more blogs about13991-08-7
