Efficient C(sp 3 )–H alkylation of fluorene and bisindolylmethane synthesis catalysed by a PNN-Ni complex using alcohols

This manuscript describes a triazolyl-pyridine nickel pincer complex that catalyzes C-alkylation of fluorenes and enables bisindolylmethane synthesis from alcohols under mild conditions with low catalyst use, broad scope, and high selectivity.
