Amidomercuriation: A General Addition of Amides and Related Compounds to Olefins

Barluenga, Jose,Jimenez, Carmen,Najera, Carmen,Yus, Miguel

, p. 591 - 593 (2007/10/02)

The addition of different carboxamides and related compounds such as urethane or urea to olefins using mercury(II) nitrate followed by sodium borohydride reduction to give the corresponding N-substituted amides, urethanes, or ureas, respectively, is described.The monoalkylated ureas, through the same amidomercuriation-demercuriation procedure, yield symmetrical and unsymmetrical N,N'-disubstituted ureas.This amidomercuriation-demercuriation process provides a new, convenient, and general method for the Markovnikov amidation of carbon-carbon double bonds.
