The acylphospholeswhich are available from dibenzophosphole and the anhydrides [RC(O)] 2 O react in ether with rigorously dried molecular oxygen to the (trifluoro)acetylphosphole oxides(2a, b), which are extremely sensitive towards nucleophiles. With stoichiometric amounts of water the P-C bond in 2a, b is cleaved hydrolytically. As a result of this hydrolysis in several reaction steps one obtains the phosphorylated alcohols(3a, b). Particularly in solution 3b is transformed quickly into the thermodynamic more stable phosphinate(4b). The chemical and spectroscopical pro­perties of the acylphospholes 1a, b and their derivatives are compared with the correspon­ding already known acyl(diaryl)phosphanes.
