Acid catalysed complexation of arenes with Cr(CO)6

Article abstract of DOI:10.1016/0022-328X(91)80047-N

Several acids were tested as potential catalysts for complexation of arenes with Cr(CO)6 in boiling decalin.Acetic acid was found to be an efficient catalyst for complexation of acyl- and acyloxybenzenes.A mixture of butanone or cyclohexanone and acetic acid, with THF and acetic acid was found to be an efficient catalytic system or complexation of other arenes.The complex (η²-acenaphthylene)4Cr(CO)2 was isolated during an attempt on acetic acid catalysed complexation of acenaphthylene with Cr(CO)6.
