Continued irradiation of W(CO)6 in the presence of excess bis(trimethylsilyl)ethyne (btmse) in n-hexane solution yields W(CO)5(η2-btmse) as the sole product, with quantum yields of 0.66 and 0.69 at λexc = 365 and 313 nm, respectively. Cr(CO)6 behav

The iron-sulfur-cluster-free hydrogenase Hmd (H(2)-forming methylenetetrahydromethanopterin dehydrogenase) from methanogenic archaea has recently been found to contain one iron associated tightly with an extractable cofactor of yet unknown structure.

Photochemical experiments with Fe(CO)3(η4-1,5-cyclooctadiene) (1) in a 13CO matrix at 10 K, monitored by means of IR spectroscopy, indicate the generation of stereoselectively labeled Fe(CO)2(13CO)(η4-1,5-cyclooctadiene) (1-1a), with 13CO in the ap
