✦ Synopsis
Reactions between the Co(I) species derived from cobalt(II1) 'salen'( and (e-ally11 or (g-but-3-enyl)
iodophenol, leads to isolatable cobalt complexes, viz (2), ( 13), which can be converted into substituted benzofurans, i.e. (S), ( 6) and benzopyrans, i.e. ( 14), ( 15); similarly interaction between (18) and Co(I) 'salen' led, in one step,
