Abstract

This work describes a new atom-economical catalytic process for the guanylation of amines with a broad substrate scope using the half-sandwich titanacarborane amide [σ:η 1:η 5 -(OCH 2 )(Me 2 NCH 2 )(C 2 B 9 H 9 )]Ti(NMe 2 ) as catalyst. This species bears two different sidearms: one is strongly bonded to the Ti center by taking the advantage of its high oxophilicity, whereas the other is hemilabile in nature, binding the Ti center reversibly.
