摘要: The lithium alkoxides [1-LiOCR1R2-2-NMe2C6H4]2 [R1 = R2 Ph (1), Cy (2)] react with BCl3 or BF3(Et2O) to give 1-X2BOCR1R2-2-NMe2C6H4 Ph, X Cl (4); R1 Cy, (5); F (6); (7)]. amide [1-LiN(Ph)C(H)Ph-2-NMe2C6H4]2 (3) reacts 1-Cl2BN(Ph)C(H)Ph-2-NMe2C6H4 (8). Compounds 4 - 8 were characterized spectroscopically (NMR, IR, MS), and crystal structures determined for 3 6.
