P–S single bonds can be generated through a variety of approaches, starting from thiols, disulfides, sulfinic acids as sulfur sources and various P(III) and P(V) coupling partners. PS–C bonds can also be formed through many comparable approaches, usually by alkylating a free phosphorous thioate anion or thioic acid.
The text describes the various approaches for creating P–S and PS–C bonds, highlighting that these methods often involve similar starting materials and coupling partners, such as phosphorus(III) and phosphorus(V) compounds and sulfur-containing molecules like thiols, disulfides, and sulfinic acids.
