Abstract

As an extension of previous work, the reactions of dimethylacetylenedicarboxylate (DMAD) with the phosphido complex [Re(PPh2)(CO)(3)(phen)] (1) and the alkylideneamido [Re(N=CPh2)(CO)(3)(bipy)] (2) were investigated. The characterization of the products by spectroscopy (IR and NMR) and X-ray diffraction revealed the coupling between DMAD, the phosphido or alkylideneamido group, and the phenanthroline (in the reaction of 1) or one of the carbonyl (in the reaction of 2) ligands, in a way consistent with initial attack of the P in 1 (or the N in 2) on one of the acetylenic carbons of DMAD.
