1,3-Dipolar additions of diazomethane, diazoethane, ethyl diazoacetate, phenyldiazomethane and phenyl azide to 7-methylthieno<2,3-c>pyridine 1,1-dioxide have been examined.The structures of the primary products e.g. 2, 8, 18, 25 have been established and their behaviour towards elevated temperatures and/or basic conditions was investigated.Under these conditions the primary products lost SO2 or N2 to yield e.g. 4, 11, 19, 21, 23, 27, 28.
