Synthesis, Characterization, and Structures of Tetrakis(2-Pyridyl)Tin Compounds
摘要:
Reactions of 2-bromopyridine and 2-bromo-6-methylpyridine with n-BuLi and tin tetrachloride afforded Sn(2-py)(4) (1a) and Sn(6-Me-2-py)(4) (1b), respectively. The identities of the two compounds were unambiguously proved by microanalyses, NMR (H-1, C-13, Sn-119) spetroscopy, and single-crystal X-ray diffraction studies.
