Diazo-2-oxoalkyl)silanes 1 react with 2-acyl-1,2,3(ฮป 3 )-[3+2] cycloreversion into 2 and 4, and extrusion of molecular nitrogen. The latter process is likely to generate 3-diazaphospholes 4 to form [3+2] cycloaddition products 5, which indicate that 1-diazo-2-silyloxy-1-alkenes 2, alkenylidene-1,2,3
