Stable ylide which reacts with aldehydes to give ɑß-unsaturated ketones. See Appendix 1. For preparation of unsubstituted vinyl ketones from this and related ylides with paraformaldehyde, see: Synthesis, 31 (1970).

Can be converted by C-acylation to a diacylphosphorane, which can be oxidized to a 1,2,3-triketone. For reaction scheme, see N,O-Bis(trimethyl­silyl)­acetamide, L00183.
