  Potential 1,1′-binaphthyl NLO-phores with extended conjugation between positions 2 and 6, and 2′ and 6′

  摘要：

  A synthetic approach is reported which allows independent introduction of alkynyl groups to positions 2,20 and then to 6,6' of binaphthyls. The approach is based on the high selectivity of the Stephens-Castro alkynylation of 6,6'-dibromo-2,2'-diiodo-1,1'- binaphthyl. The tetraalkynylated derivatives exhibit extended conjugation between groups at positions 2 and 6, and 20 and 60, achieved by overcoming steric hindrance at positions 2 and 2' by using alkynyl spacers.
