Various xanthates can be added to N-vinyl phthalimide with little formation of oligomers, if the xanthate is used in excess and the medium slightly diluted. The adduct xanthates thus obtained can in turn undergo radical additions to numerous olefins, providing a convergent and modular access to densely functionalized amines. (C) 2010 Elsevier Ltd.

An expedient approach for the intermolecular C-H functionalization of pyrazines and other heteroarenes by the radical chemistry of xanthates is reported. Incorporation of a multitude of functional alkyl groups onto these heteroarenes proceeds in good yield and good to excellent regioselectivity, leading to highly functionalized heteroaromatics.
