- On Triazoles XXXI. The Reaction of 1,2,4-Triazolylcarbothiohydrazides with Homo- and Heterocyclic Ketones. An Unexpected Reaction Leading to 4,5-Polyalkylene Thiazoles
-
The reaction of 1,2,4-triazolylcarbothiohydrazides with homo- and heterocyclic ketones to yield 8-spirotriazolotetrazepine-5-thiones 7 (n = 4, 5, 6, 7 and 11), 8 and 9, respectively, all representing movel ring systems was studied.Providing the reaction at higher temperature a novel reaction was observed to yield 4,5-polyalkylene thiazoles for which a mechanism is proposed.

-
The title compounds have been prepared in good yield by treating the corresponding 2,n-dibromocycloalkanone with LiCuPh2.Single-crystal X-ray structures are reported for cis- and trans-2,12-diphenylcyclododecanone.
