The lithium alkoxides [1‐LiOCR 1 R 2 ‐2‐NMe 2 C 6 H 4 ] 2 [R 1 = R 2 = Ph ( 1 ), Cy ( 2 )] react with BCl 3 or BF 3 (Et 2 O) to give 1‐X 2 BOCR 1 R 2 ‐2‐NMe 2 C 6 H 4 [R 1 = R 2 = Ph, X = Cl ( 4 ); R 1 = R 2 = Cy, X = Cl ( 5 ); R 1 = R 2 = Ph, X = F ( 6 ); R 1 = R 2 = Cy, X = F ( 7 )]. The lithium amide [1‐LiN(Ph)C(H)Ph‐2‐NMe 2 C 6 H 4 ] 2 ( 3 ) reacts with BCl 3 to give 1‐Cl 2 BN(Ph)C(H)Ph‐2‐NMe 2 C 6 H 4 ( 8 ). Compounds 4 ‐ 8 were characterized spectroscopically (NMR, IR, MS), and crystal structures were determined for 3 ‐ 6 .
