in tetrahydrofuran
a THF soln. of carbanion was treated at -78°C under Ar with PhCOOMe, stirred 3 h at -78°C and allowed to warm to 25°C overnight; a 10percent soln. of KH2PO4 was added at 0°C, mixt. was extd. with 5:1Et2O-CH2Cl2, washed with satd. NaCl, dried over MgSO4, distilled to give PhC(O)CH2SiMe3 containing 14percent of bis(pinacol) diborate (the latter wasidentified by (1)H NMR data);
