《Hydrosilylation of Aldehydes and Ketones Catalysed by Bis(phosphinite) Pincer Platinum Hydride Complexes》 was published in Advanced Synthesis & Catalysis in 2020. These research results belong to Chang, Jiarui; Fang, Fei; Zhang, Jie; Chen, Xuenian. SDS of cas: 873-75-6 The article mentions the following:
Bis(phosphinite) pincer platinum hydride complexes, [2,6-(R2PO)2C6H3]PtH (R = tBu, iPr), were synthesized, characterized and applied to the hydrosilylation of aldehydes and ketones. NMR study and single crystal X-ray diffraction anal. indicated that the hydrides in these two platinum complexes are comparatively less hydridic: down-field 1H NMR resonances (0.71 and 0.98 ppm) and weak Pt-H interactions were observed Both the platinum complexes were found to be good catalysts for the hydrosilylation of aldehydes and ketones with phenylsilane. The corresponding alcs. were isolated in good to excellent yields following basic hydrolysis of the resultant hydrosilylation products and turnover frequencies (TOFs) up to 3200 h-1 were achieved at 60° in toluene, which are much higher than those of the hydrosilylation catalyzed by the corresponding nickel pincer hydride complexes. A possible mechanism for the present hydrosilylation process was discussed. The results came from multiple reactions, including the reaction of (4-Bromophenyl)methanol(cas: 873-75-6SDS of cas: 873-75-6)
(4-Bromophenyl)methanol(cas: 873-75-6) undergoes three-component reaction with acetylferrocene and arylboronic acid to give ferrocenyl ketones containing biaryls.SDS of cas: 873-75-6 It undergoes efficient trimethylsilylation reaction with 1,1,1,3,3,3-hexamethyldisilazane in the presence of catalytic amount of aspartic acid in acetonitrile.
