According to kinetic measurements,the 1,3-cycloadditions of diphenyl-diazomethane to thioketones are much faster than those to α,β-unsaturated carbonyl compounds and nitriles previously regarded as record dipolarophiles.The primary cycloadducts are tetrasubstituted 1,3,4-thiadiazolines which extrude N2 and furnish thiiranes via thiocarbonyl ylides.

In contrast to a literature report, diazomethane and diazoacetic ester add to the CC double bond of tetracyanoethylene and ethylenetetracarboxylic ester.The behavior of the 1- and 2-pyrazolines deviates from the rule.
