Reaction of thianthrene cation radical perchlorate (1) with tert-butyl peroxide (TBP) in acetonitrile gave thianthrene (2), thianthrene 5-oxide (3), cis-thianthrene-5,10-dioxide (4), 5-acetonylthianthrenium perchlorate (9), along with small amount of ...
Reaction of thianthrene cation radical perchlorate (1) with tert-butyl peroxide (TBP) in acetonitrile gave thianthrene (2), thianthrene 5-oxide (3), cis-thianthrene-5,10-dioxide (4), 5-acetonylthianthrenium perchlorate (9), along with small amount of thianthrene-5,5-dioxide (7) in some cases. Isolation of N-tert-butylacetamide indicated the formation of tert-butyl cation from TBP. The formation mechanisms of these products were proposed.
