Preparation of O-Diorganoboryl Derivatives of Several (Organo)-Phosphorus Acids1)The O-diorganoboryl derivatives 4 - 9 of (organo)-phosphorus acids are prepared from diphenylphosphinic acid (1a), dicyclohexylphosphinic acid (1b), phenylphosphinic acid (1c), phenylphosphonic acid (2), and phosphoric acid (3) using activated triethylborane (method A), bis-9-borabicyclo[3.3.1]nonane (method B), or tetraethyldiboroxane (method C). By O-diorganoborylation, 1a - c give the compounds RR′P(O)OB(C2H5)2 [R = R′ = c-C6H11 (4b); R = C6H5, R′ = H (4c)], RR′P(O)OBC8H14 [R = R′ = C6H5 (5a); R = R′ = c-C6H11 (5b); R = C6H5, R′ = H (5c)], 2 reacts to form C6H5P(O)(OBR2)2 [R2 = (C2H5)2(6); R2 = C8H14 (7)], and 3 yields the compounds OP(OBR2)3 [R2 = (C2H5)2(8); R2 = C8H14 (9)]. - The IR and MS data for 4 - 9, which associate in solution, are discussed.
Notizen:
Die O-Diorganoboryl-Derivate 4 - 9 von (Organo)-Phosphor-Säuren werden aus Diphenylphosphinsäure (1a), Dicyclohexylphosphinsäure (1b), Phenylphosphinsäure (1c), Phenylphosphonsäure (2) und Phosphorsäure (3) mit aktiviertem Triethylboran (Methode A), Bis-9-borabicyclo[3.3.1]nonan (Methode B) oder mit Tetraethyldiboroxan (Methode C) hergestellt. Unter O-Diorganoborylierung erhält man aus 1a - c die Verbindungen RR′P(O)OB(C2H5)2 [R = R′ = C6H5 (4a); R = R′ = c-C6H11 (4b); R = C6H5, R′ = H (4c)], RR′P(O)OBC8H14[R = R′ = C6H5 (5a); R = R′ = c-C6H11 (5b); R = C6H5, R′ = H (5c)], aus 2 die Verbindungen C6H5P(O)(OBR2)2[R2 = (C2H5)2 (6); R2 = C8H14(7)] sowie aus 3 die Verbindungen OP(OBR2)3 [R2 = (C2H5)2 (8); R2 = C8H14 (9)]. - Für die in Lösung assoziierten Verbindungen 4 - 9 werden IR- und MS-Daten angegeben.
