“…Although (η 5 -C 5 H 5 ) 2 Os 2 (CO) 4 , III , was first reported almost 40 years ago, we were surprised by the complete absence of photochemical studies in the literature. Indeed the only photochemical study of a derivative of III appears to be that of Johnson and Baird, who have shown that solution photolysis of (η 5 -C 5 Me 5 )Os(CO) 2 CH 2 Ph in the presence of PMe 2 Ph results in the formation of exo -(η 4 -C 5 Me 5 CH 2 Ph)Os(CO) 2 PMe 2 Ph by what was believed to be a radical mechanism. The paucity of photochemical studies is certainly due to the expense of the osmium starting materials and the difficulties associated with the synthesis of III and its derivatives.…”
