摘要: Abstract The reaction of BEt 3 with the (2-dimethylaminophenyl)alcohols 1-HOX-2-NMe 2 C 6 H 4 [X = CPh ( 1 ), CCy CPh CH )] [1:1 (for – ) or 1:2 in presence t BuCO as catalyst gave derivatives 1-Et BOX-2-NMe 5 7 and BEt(1-OCPh -2-NMe 8 ). Treatment acetic acid 1-(CH COO)EtBOCCy Compounds were characterized spectroscopically (NMR, IR, MS). Crystal structure determinations carried out on , . For chiral compound both enantiomers are present unit cell.
