Phosphoranes (I) and (II) also readily undergo addition at the triple bond in phenylacetylene to give functionally substituted quasiphosphonium ylids (III) and (IV), which have been previously obtained only with difficulty. Ylids (III) and (IV) are c

The possibility is discussed of using tautomerism to determine the conformational free energies of ring substituents, and the free energy of steric interaction of the substituents in the individual stereoisomers of 1-phenyl-3-carbomethoxyphosphorinan

1. The formation of stable alkoxyphosphoranes is observed when a phenolic Mannich base, containing o-substituents in the benzene ring, is reacted with trialkyl phosphites. 2. The properties of the alkoxyphosphoranes were studied: hydrolysis, thermal

Autor: E. I. Gol'dfarb, O. V. Voskresenskaya, É. T. Mukmenev, P. A. Kirpichnikov, N. P. Anoshina

Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 21:1339-1343

The previously expressed theory that the tricyclic triethyl triphosphite of D-mannitol is 2-ethoxy-4, 5-bis-(2′-ethoxy-1′, 3′, 2′-dioxaphospholan-4′-yl)-l,3,2-dioxa-4-phospholane was corroborated on the basis of the differential-thermal ana
