A new mechanism for nucleophilic substitution at a thiophosphoryl centre revealed by the reaction of diisopropylamine with PSCl3
Abstract
The reaction of PSCl3 with Pri2NH at 60 °C affords the disubstitution product (Pri2N)2P(S)Cl without first forming the monosubstitution product Pri2NP(S)Cl2; a PIII compound (possibly PCl3) generated in situ seems to be a crucial intermediate.
