The synthesis and reactions of 2,11-diselenametacyclophanes. An investigation of the selenoxide elimination route to metacyclophane-1,8-dienes

2,11-Diselenametacyclophane and its 9,18-dimethyl derivative are prepared in ca. 7percent yield from Na2Se and xylylene bromide.Wittig rearrangement and benzyne induced Stevens rearrangement gave the ring contracted metacyclophane derivative.Attempted selenoxide elimination to produce metacyclophane-diene failed.The 1Hmr spectra of the selenametacyclophane indicate that the syn-conformer is the more stable.A general synthesis of aryl-alkenes in an 80percent yiels starting from benzyl phenyl selenide, alkylation with an alkyl halide, and then selenoxide elimination is given.
