Alkene homologation: via visible light promoted hydrophosphination using triphenylphosphonium triflate
Levin, Vitalij V.,Dilman, Alexander D.

A hydrophosphination reaction of alkenes with triphenylphosphonium triflate under photocatalytic conditions is described. The reaction is promoted by naphthalene-fused N-acylbenzimidazole and is believed to proceed through intermediate formation of a phosphinyl radical cation. The resulting phosphonium salts are directly involved in the Wittig reaction leading to homologated alkenes.
Reductive Alkylation/Arylation of Arylcarbinols and Ketones with Organosilicon Compounds
Cella, J. A.

Arylcarbinols react with certain organosilanes in the presence of boron trifluoride to yield hydrocarbons resulting from transfer of an R group from silicon to carbon.The transfer works well with aryl- and allylsilanes and fails with alkylsilanes.Allylation of ionizable carbinols is sometimes accompanied by cation-mediated oligomerization.This can be offset by converting the carbinols in question to their respective allyldimethylsilyl ethers followed by rearrangement of the ethers with BF3.While diaryl ketones are sluggishly bisallylated, the corresponding ketals undergo smooth bisallylation at 0 deg C with allytrimethylsilane/BF3/CH2Cl2.
