Tautomerism in 1,3,2,5-dioxaborataphosphorinanes and their analogs
摘要:
In solutions ammonium 2,2,5-triphenyl-4,6-di-R-1,3,2,5-dioxaborataphosphorinanes are characterized by ion-complex tautomerism. The complex form dissociates reversibly to a secondary phosphine and an aldehyde. The reaction of tris(hydroxymethyl)phosphine with isobutyl diphenylborate in the presence of formaldehyde and a tertiary amine gave 5,5'-spirobi(2,2-diphenyl-1,3,2,5-dioxaborataphosphorinanes).
