摘要:
A novel procedure has been developed for selective synthesis of N-aryl-1,3,5-dithiazinanes, 1,2,6,7-tetrahydro-3,5,1,7-benzodithiadiazonine, and 6,7-dihydro-1,3,5,7-benzotrithiazonine by reactions of aniline derivatives with N-methyl-1,3,5-dithiazinane or 1,3,5-trithiane in the presence of transition and rare earth metal salts and complexes.

Cyclothiomethylation of o-phenylenediamine with CH2O and H2S gives rise to 1,2,4,5-tetrahydrobenzo[d][1,3,6]thiadiazepine and 1,2,6,7-tetrahydrobenzo[f][1,3,5,8]dithiadiazonine, whereas m-phenylenediamine forms benzothiaza macroheterocycles of various structure, comprising 4-8 molecules of the starting diamine, formaldehyde, and hydrogen sulfide. 4,4'-Diaminodiphenyls give bis(1,3,5-dithiazinanes), along with oligomeric hetero(N,S,O)atomic compounds.
