A practical, scalable electrochemical dehydrogenative cross-coupling of P(O)H compounds with thiols, phenols and alcohols in both an undivided cell and a continuous-flow setup is disclosed. Its broad substrate scope (>50 examples), good functional-group tolerance and scalability (>10 g) show potential for practical synthesis. A preliminary mechanistic study suggests that the phosphorus radicals are

A phase-transfer catalytic (PTC) alkylation involving the reaction of alkyl bromide and dialkyl/diarylthiophosphinic acids in the presence of potassium carbonate and tetrabutylammonium bromide is described. The reaction proceeds by SN2 mechanism and gives exclusively S-alkylated products.
