| titleOfInvention | PROCEDURE FOR THE MANUFACTURE OF SUBSTITUTED BLUES IN POSITION 4, 6, 8 |
| abstract | Complexes are formed between an azulene substituted in the 4- and 8-positions and an alkali metal alkyl, aryl, or aralkyl or a complex thereof with a metallo-hydrocarbon compound. The organo-metallic compound used may be any of those referred to in Specification 808,181. In the examples complexes are formed between 4, 8-dimethylazulene and lithium methyl, lithium ethyl, lithium n-propyl, lithium butyl and lithium phenyl, 4, 8-diphenylazulene and lithium butyl and 4-methyl-8-phenylazulene and lithium phenyl, in solution in ether but are not isolated.ALSO:Azulenes substituted in the 4, 6 and 8 positions are obtained by further treating a 4,8-disubstituted azulene by the process of Specification 808,181 which comprises reacting with an alkali metal alkyl, aryl or aralkyl or metallo-hydrocarbon complex thereof to form an addition compound which is either treated with a compound containing an active hydrogen atom, e.g. water or an alcohol, followed by dehydrogenation of the dihydroazulene so formed, e.g. in the presence of chloranil, or direct thermal decomposition, e.g. by steam distillation, to the 4,6,8-trisubstituted azulene. The preparations described include those of the new compounds 4,8-dimethyl-6-ethyl (or -propyl or -butyl or -phenyl)-azulene, 4,8-diphenyl-6-butyl - azulene and 4 - methyl - 6,8 - diphenyl-azulene. |
