Transition metal complexes include a diazaphosphacycle of formula III and a transition metal. The phosphorus atom of the diazaphosphacycle is bonded to the transition metal and the diazaphosphacycle of formula III has the following structure where the variables have the values set forth herein.

Diazaphosphacycle transition metal complexes

Diazaphosphacycles comprising compounds having the formula XI and salts of the compound are provided, wherein the variables W, T, R, R, and Rare as described herein. Transition metal catalysts incorporating such diazaphosphacycles and methods of use thereof are also disclosed. There are further provided compositions comprising diazaphosphacycles covalently attached to a solid support and methods of use thereof. 

Diazaphosphacycles

A diazaphosphacycle may be synthesized by reacting a phosphine with a diimine and optionally one or more equivalents of an acid halide, a sulfonyl halide, a phosphoryl halide, or an acid anhydride in the substantial absence of Oto form the diazaphosphacycle. The phosphine has the formula R&#x2014;PHwhere Ris a substituted or unsubstituted aryl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted cycloalkyl group, or a substituted or unsubstituted ferrocenyl group.
