Visible-light-mediated benzylic sp3 C–H bond functionalization to C–Br or C–N bond
摘要:
A visible-light-promoted functionalization of unactivated benzylic sp(3) C-H bonds was developed. Ethylbenzene derivatives were converted to the corresponding benzyl bromides or afforded benzylamine derivatives in a one-pot manner under visible light photoredox conditions. (C) 2016 Elsevier Ltd.

Thioamides, readily available from aldehydes, sulfur and secondary amines, can be converted to unsymmetrical ketones by the carbophilic addition of organolithiums to the thiocarbonyl group. Reduction of the intermediates with lithiumaluminumhydride gives α-alkylated or α-arylated amines.
