Article abstract of DOI:10.1021/ja00327a015

Conversions of cationic manganese tricarbonyl comlexes of toluene, 1a, o-xylene, 1b, biphenyl, 1c, and anisole, 1d, to free cyclohexa-1,3-dienes are reported.The reaction sequence involves double hydride reduction of 1a-d and protonation to give the M-H-C
