2-Methylbenzoxazole can be lithiated at the methyl group to give a dimer (6) which reacts with various-element halides (PhBCl2, Ph2SnCl2, Me2SiCl2) to give the new chelate complexes (7).Reaction of 6 with two equivalents of (E)-2-(chloro)dimethylstannyl-3-diethylboryl-2-pentene yields a new polycyclic compound (8) which contains five-coordinate tin (a chiral centre), and four-coordinate boron.No dimer corresponding to 6 was obtained when 2-methylbenzothiazole was lithiated.The new compounds have been characterized 1H, 11B, 13C, 29Si, 119Sn NMR spectroscopy and by elemental analyses.
