The reaction of 1-adamantyl azide (N 3Ad) with [Cr(CO) 3Cp] 2 under Ar results in conversion of N 3Ad to 1-adamantyl isocyanate (OCNAd) and [Cr(CO) 2Cp] 2. Two reaction intermediates were detected: 3Cr 2(CO) 5Cp 2 and an electron spin resonance active complex proposed to be Cr(CO) 2(O-C-NAd)Cp. Under a CO atmosphere, 3Cr 2(CO) 5Cp 2 regenerates [Cr(CO) 3Cp] 2 and approximately five turnovers can be achieved. Hydrogenation of N 3Ad by HMo(CO) 3Cp yields H 2NAd, N 2, and [Mo(CO) 3Cp] 2. N 3Adreacts with Mo(CO) 3(P iPr 3) to form Mo(N 3Ad)(CO) 3(P iPr 3) 2, which slowly isomerizes to Mo(κ 2-Pr 3PN 3Ad)(CO) 3(P iPr 3), the structure of which is reported.
