The paramagnetic tetrahydride cluster, Cp*[sub 3]Co[sub 3]([mu][sub 2]-H)[sub 3]([mu][sub 3]-H) (1) reacts with acetylene to ultimately form the bis(ethylidyne) cluster Cp*[sub 3]Co[sub 3]([mu][sub 3]-CCH[sub 3])[sub 2] (2). Two intermediates were detected during the course of the reaction: the diamagnetic Cp*[sub 3]Co[sub 3]([mu][sub 2]-H)[sub 3]([mu][sub 3]-CCH[sub 3]) (3) and the paramagnetic Cp*[sub 3]Co[sub 3]([mu][sub 3]-H)([mu][sub 3]-CCH[sub 3]) (4). Cluster 3 loses H[sub 2] in refluxing toluene to generate 4, and 4 reacts with H[sub 2] at 80[degrees]C to generate 3. Kinetic analysis indicates 3 and 4 are both formed directly from cluster 1. 21 refs.
