Chlorine nuclear quadrupole resonance of phosphorus–chlorine compounds
Abstract
The 35Cl n.q.r. frequencies at 77 K of two chloro(phenyl)phosphoranes, four cyclic phosphorus esters, four phosphoryl and thiophosphoryl chlorides, and eight chlorophosphates, are reported. The frequencies are used to predict possible molecular structures, and are related to σ- and π-bond effects within the molecules, by use of BEEM.
