Catalytic cyclization and competitive deactivation with Ru(PR2NR'2) complexes

J M Stubbs et al. Dalton Trans. .

Abstract

The first successful use of the PR2NR'2 (1,5-R'-3,7-R-1,5-diaza-3,7-diphosphacyclooctane) ligand family toward an organic synthesis is described. The precatalysts [Ru(Cp)(PR2NBn2)(MeCN)]PF6 are active toward cyclization of 2-ethynylbenzyl alcohol at low catalyst loading and mild temperatures. Catalyst performance however is limited by both low conscription and by competitive deactivation.
