The active nickel complex generated in situ by reduction of NiBr2(PPh3)2 with zinc in the presence of Et4NI is a useful reagent for the dehalogenative coupling of 2-bromo-1,6methano[lO]annulene and 1-brcmo-and 1,3-dibromoazulenes.
## Abstract ESR. and ENDOR. spectra are reported for the radical anion of the 2βmethyl derivative (III) of 1,6βmethano[10]annulene (I). Comparison of the hyperfine data for IΒ·β and IIIΒ·β with those for the radical anions of naphthalene (II) and its 1βmethyl derivative (IV), respectively, confirms t
