Ion association in chloroform solution increases in increasing alkyl chain length (R) in the phosphonium moiety and decreases going from diaryl phosphate (PP) to diaryl thiophosphate (PTP). [Display omitted] •PPs & PTPs behave differently in terms of their NMR behavior in chloroform solutions.•P...
