Abstract

[Os₄H₃(CO)₁₁CH:CHR] reacts with CO under pressure to give edge bridging methylenic compounds [Os₄H₂(CO)₁₂CHCH₂R] and, when R = H, with acetylenes, R′C₂R″, to give π-allylic derivatives of the form [Os₄H₂(CO)₁₁MeCCR′CHR″]; the structures of these two compounds have been confirmed by X-ray diffraction analyses.
