Cyclic carboxylic monophosphides: a new class of phosphorus heterocycle
Abstract
Bis(trimethylsilyl)phosphines, RP(SiMe3)2(R = Ph, But), react with di-acid chlorides or the corresponding acid anhydrides to afford cyclic carboxylic monophosphides featuring five-, six- or seven-membered phosphorus-containing rings; the reaction chemistry of the five-membered ring is discussed.
