Abstract

Only the 1,2-diphosphacyclobutadiene and none of its 1,3 isomer was obtained in the reaction of 1 with tBuC≡P to give 2. In complex 1, which was prepared from [TaCl₂(η⁵-C₅Me₅)(CO) ₂(thf)] and tBuC≡P, the phosphaalkyne adopts an η²(4e) bonding mode according to NMR data, crystal structure analysis, and theoretical calculations.
