Wittig condensation of (Z)-2-pentenylidene triphenylphosphorane (14) and 7-tert.-butoxy-heptanal (13) under conditions of phase transfer catalysis and subsequent conversion into the corresponding acetate afforded a mixture of 28percent 7(E),9(Z)-dodecadien-1-yl acetate, the sex pheromone of Lobesia botrana, along with the other geometrical isomers and 30percent unidentified by-products.The synthons 14 and 13 were prepared starting with (Z)-2-butene-1,4-diol (1) and hexane-1,6-diol (9), respectively.

The chemistries of 1,8-naphthalenedicarboximidyl (N.) and phthalimidyl (P.) radicals are described.Hydrogen abstractions from alkanes and additions to olefins and benzene proceed in high yield.The low cost of phthalimide, coupled with the absence of a parasitic ring-opening reaction for P., makes N-bromophthalimide an economical reagent for low-selectivity brominations.The chemistry of N. resembles that of other imidyl radicals (succinimidyl, glutarimidyl) with respect to selectivities.Conversely, P. is somewhat of a maverick among imidyl radicals, being slightly more selective in its reactions, but still 102-103 less selective than Br..
