An unusual transition metal-free cascade reaction of alkynyl carbonazidates was discovered to form azasilacyclopentenes. Mild thermolysis afforded the products via a series of cyclizations, rearrangements, and an α-silyl C–H bond insertion (rather than the more common Wolff rearrangement, 1,2-shift, or β-silyl C–H insertion) to form silacyclopropanes. A mechanistic proposal for the sequence was informed
