A half-sandwich 1,2-azaborolyl (Ab) ruthenium complex, (Ab-C[triple bond, length as m-dash]CPh)RuCl(PPh3)2 (), has been synthesized by treating RuCl2(PPh3)3 with lithium 1,2-azaborolide L-1, or by treating either RuCl2(PPh3)3 or RuHCl(PPh3)3 directly with 1,2-azaborole LH-1. It is evaluated as a suitable precatalyst in [2 + 2] cycloadditions of norbornene derivatives with DMAD and in atom transfer radical additions of halogenated compounds with olefins.
