The compounds S(6-
t -Bu-4-Me-C6H2O)2P(O)Cl (1 ), CH2(6-t -Bu-4-Me-C6H2O)2P(O)Cl (2 ) and (2,2′-C20H12O2)P(O)Cl (3 ) react with diazabicycloundecene (DBU) to give rise to, predominantly, the phosphonate compounds [S(6-t -Bu-4-Me-C6H6O)2P(O)(DBU)]+[Cl]− (4 ), [CH2(6-t -Bu-4-Me-C6H2O)2P(O) (DBU)]+[Cl]− (5 ) and [(2,2′-C20Hi2O2)P(0)(DBU)]+[Cl]- (6 ). The first two compounds could be isolated in the pure state. In analogous reactions of 1 and 2 with diazabicyclononene (DBN) or N-methyl imidazole, only the pyrophosphates [S(6-t -Bu-4-Me-C6H2O)2P(O)]2O (7 ) and [CH2(6-t -Bu-4-Me-C6H2O)2P(O)]2O (8 ) could be isolated, although the reaction mixture showed several other compounds in the phosphorus NMR. A possible pathway for the formation of phosphonate salts is proposed. The X-ray crystal structures of4 ,7 and8 are also discussed.
