Regiodivergent and Stereoselective Hydrosilylation of 1,3-Disubstituted Allenes


, : Regiodivergent and Stereoselective Hydrosilylation of 1,3-Disubstituted Allenes. Angewandte Chemie 54(31): 9088-9091

Methods for the highly stereoselective and regiodivergent hydrosilylation of 1,3-disubstituted allenes have been developed. The synthesis of E allylsilanes is accomplished with palladium NHC catalysts, and trisubstituted Z alkenylsilanes are accessed with nickel NHC catalysts. Unsymmetrically substituted allenes are well tolerated with nickel catalysis and afford Z alkenylsilanes. Evidence for a plausible mechanism was obtained through an isotopic double-labeling crossover study.

Photolysis of optically active aminocarbene chromium complexes with N-protected imidazolines produced alpha-amino-N-protected azapenams in good yield and with high diastereoselectivity. Removal of the protecting group resulted in cleaving of the b...

Effect of contamination on antibody production in relation to residue level in organs. The organophosphorus insecticide trichlorphon was tested at medium (10 and 20 ppm) and high concentrations (20,000 ppm) on antibody production against Yersinia ruckeri vaccine. No statistically significant effect was observed on humoral response o...
