The methoxy-substituted bis-1,2,3-dithiazolyl radical 4a thermally decomposes to afford the zwitterionic bis-1,2,3-dithiazolopyridone 5a; EPR spectroscopic analysis indicates a rearrangement of the radical prior to loss of the methyl group.

Reaction of the acetylene Mes(2)P-C≡C-Ar with B(C(6)F(5))(3) at rt gives a zwitterionic phosphirenium product, which reacts further at >100 °C to complete the 1,1-carboboration reaction.
