Previously unknown bis{[2-(4-tert-butyl)phen]ethyl}phosphine sulfide is obtained with a high yield from 4-tert-butyl styrene, red phosphorus, and elemental sulfur. Using single crystal XRD, multinuclear NMR, IR, and UV spectroscopy, it is found that the phosphorus atom is four-coordinated in the bis{[2-(4-tert-butyl)phen]ethyl}phosphine sulfide molecule (regardless of the phase state of the compound: Crystal, solution). By the example of phosphorylation of bis{[2-(4-tert-butyl)phen]ethyl}phosphine sulfide acetylene in the KOH-DMSO system it is shown that the reaction proceeds by double addition with the participation of phosphorus-centered nucleophiles.
