New Organometallic Derivatives of 1,6-Methano[10]annulene
摘要:
The reverse addition of 2-lithio-1,6-methano[10]annulene (2-lithio-1,6-methanocyclodecapentaene) to some group VI metal carbonyl compounds followed by alkylation with Meerwein salts gave the E. O. Fischer transition metal complexes in good to excellent yields. Cyclization of the chromium complex with diphenylacetylene is achieved in moderate yield.
