摘要:
Cyclization of aliphatic moieties of 3-20 carbons which comprises contacting a suitable starting compound comprising the aliphatic moiety with a catalyst comprising at least one member selected from the group consisting of copper aluminum borate and zero valent copper on a support comprising aluminum borate under appropriate reaction conditions to obtain a compound having at least one more cyclic moiety than the starting compound. Preferably, the aromatic which undergoes cyclization is an alkenyl group attached to an aromatic nucleus. The present invention can be used to dehydrocyclize alkenylbenzenes to alkylnaphthalenes. In particular, 5-(o-tolyl)pentene can be dehydrocyclized to mixtures of 1,5-, 1,6-, and 2,6-dimethylnaphthalene.

The present invention is a cyclization process utilizing the catalyst copper aluminum borate which process comprises the step of contacting (1) a compound having a fragment in which a carbon-containing chain of at least three atoms in sequence is bonded at one end thereof to a nitrogen, oxygen, or sulfur atom, and at the opposite end to a carbon, nitrogen, oxygen, or sulfur atom, where the latter are bonded to at least one hydrogen atom; with (2) a catalyst comprising at least one member selected from the group consisting of copper aluminum borate and zero valent copper on a support comprising aluminum borate, under conditions sufficient to effect ring closure between the ends of the fragment to obtain a compound comprising a heterocyclic ring.
摘要:
A dehydrocyclization process is described for producing polynuclear organic compounds by contacting a starting organic material having at least one ring moiety comprising at least two adjacent ring carbon atoms each bonded to an independently selected monovalent radical comprising at most about eight carbon atoms provided at least one of the monovalent hydrocarbon radicals comprises more than one carbon atom with a crystalline copper aluminum borate catalyst. The preferred catalyst comprises at least one member selected from the group consisting of (a) crystalline copper aluminum borate and (b) zero valent copper on a support comprising at least one member selected from the group consisting of Al.sub.4 B.sub.2 O.sub.9 and the crystalline copper aluminum borate, the zero valent copper on the support being formed by the reduction of the crystalline copper aluminum borate. The process is conducted under conditions sufficient to effect cyclization between (i) a carbon atom of one of the radicals and (ii) a carbon atom of the other radical forming a dehydrocyclization product comprising a polynuclear compound wherein the new ring comprises at least 5 carbon atoms.
