DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 24 Reaction of the squaric acid amides I with (RNR1 = pyrrolidino, Ph2N, morphine, etc.) gave phosphonium salts II in moderate-to-good yields. (2-Phenyl-3,4-dioxocyclobutenyl)triarylphosphonium chlorides III [R2 = (un)substituted Ph] were obtained similarly from phenylchlorocyclobutenediones and triarylphosphines. The phosphonium betaine IV is generated in a 3-component reaction from perchlorocyclobutenone, Ph3P and H2O. .
