yields, increased diversity of the alcohol substrate scope, and high E/Z selectivity. Furthermore, the reaction proceeds under mild conditions and yields up to 98%. Computationalstudies provide a rationalization for a mechanistic pathway for the retention of E/Z stereochemistry when E or Z alkenyl silanes are used as nucleophiles. This methodology is complementary to existing methodologies for deoxygenative
The Friedel-Crafts-type benzylation of various -excessive heteroaromatic and aromatic compounds with trityl or benzhydryl halides was efficiently promoted by a thiourea catalyst. This is a novel example of thiourea catalysis of aromatic alkylation by way of an S(N)1 pathway.

Fe(OTf) 3 -catalyzed reaction of benzylic acetates withallyltrimethylsilane, azidotrimethylsilane, and cyanotrimethylsilane affordedthe corresponding allylated, azido, and cyano products in high yields.2-Trimethylsilyl-substituted benzofuran and indole worked well tofurnish the benzyl-substituted benzofuran and indoles.
