<i>m</i>-Terphenyl-Substituted Amidinates:  Useful Ligands in the Preparation of Robust Aluminum Alkyls Deepa Abeysekera Katherine N. Robertson T. Stanley Cameron Jason A. C.

The amidines are prepared in a one-pot reaction using 2,4,6-triphenylphenyllithium (formed <i>in situ</i> by the reaction of 2,4,6-triphenylphenylbromide with <i>n</i>-butyllithium) with dialkylcarbodiimides (RNCNR, R = cyclohexyl or isopropyl). An aqueous workup of the reaction mixtures results in the formation of sterically demanding amidines <b>2H</b> and <b>3H</b>. The amidines react readily with trimethylaluminum to form dialkylaluminum amidinate complexes. Two complexes have been prepared and comprehensively characterized in the solid state using single-crystal X-ray crystallography. In the crystalline state, dialkylaluminum amidinates are robust complexes that can be easily handled in air for short periods of time without noticeable decomposition. 2001-11-29 00:00:00 dialkylaluminum amidinates dialkylaluminum amidinate complexes RN 3 H Robust Aluminum Alkyls reaction mixtures results amidines 2 H form dialkylaluminum amidinate complexes
