Dichalcogenophosphinic acids

Dichalcogenophosphinic acid (dichalcogenophosphinate) Dichalcogenophosphoric acid (dichalcogenophosphate) Dichalcogenophosphonic acid (dichalcogenophosphonate)... [Pg.287]

Secondary phosphine chalcogenides (15a) can be readily prepared from oxidation of secondary phosphines (R2PH) with elemental sulfur, selenium or tellurium, although care must be taken to avoid over-oxidation to give the dichalcogenophosphinic acids (see Section 5.2.5). [Pg.295]

Hence, chalcogenoamidophosphinic acids of general formula R2P(E)NHR (27) can be considered as dichalcogenophosphinic acids with one of the chalcogen atoms replaced by an amido group. These amido species are still normally referred to as acids due to their acidic amide protons. They are accessible from reaction of thiophosphinic chlorides and primary amines (Equation 43) or from reaction of aminophosphines with elemental chalcogen... [Pg.302]
