Abstract
The mechanism of the reaction of 3,3-dimethyl-2-trimethylsiloxy-1-trimethylsilyl-1-phosphabut-1-ene with bis(phenylendioxy)chlorophosphorane was studied by the density functional theory method. According to the quantum chemical calculations this interaction occurs in parallel on two reaction centers: PII atom (electrophilic substitution) and O atom (nucleophilic substitution).
