Molybdenum complexes sandwich compounds

Methyl benzoate, anisole, and diphenyl ether each give sandwich compounds with chromium vapor, although in rather low yield (32, 55, 110). Chromium appears to attack alkyl ethers and this deoxygenation probably competes with complexation with the aromatic oxygen compounds. No simple product has been isolated from chromium atoms and aniline, but bis(7V,7V-dimethylaniline)chromium has been prepared (32). The behavior of molybdenum and tungsten vapors closely resembles that of chromium in reactions with oxygen- and nitrogen-substituted arenes (113).

The only sandwich complex of molybdenum possessing both a seven-carbon and a six-carbon ring has been prepared by reaction of [MoI(CHT)(CO)2] with NaBPh4 [cf. reactions (11.7)-(11.10)]. This compound represents a unique zwitterionic sandwich containing the large f/ -bonding tetraphenylborato ligand...
