| abstract | 1299545 Dehydrocoupling aromatic hydrocarbons HERCULES Inc 16 Dec 1970 [29 Dec 1969] 59807/70 Heading C5E [Also in Division C2] A process for coupling aromatic compounds of the formula R-Ar-X (in which Ar is an aromatic nucleus, and each of R and X is H or C 1-3 alkyl) comprises contacting the aromatic compound with a mercuric salt and at least a catalytic amount of a noble metal salt in liquid hydrogen fluoride as the reaction medium, the salts being in solution in the liquid H.F. and the noble metal salt being a salt of palladium, rhodium, ruthenium or gold. The mercuric and noble metal salts may be fluorides which are formed in situ by reaction of the H.F. with a mercury or noble metal compound or a noble metal itself. The aromatic nucleus Ar may be, for example, a benzene, naphthalene, biphenyl or anthracene nucleus. Examples describe the preparation of tetramethylbiphenyls from o-oxylene; and binaphthyl from napthlalene. |
