    描述:
    反式-2-己烯醛二甲基乙缩醛 在 tin(ll) chloride 作用下, 以 二氯甲烷 为溶剂, 反应 1.0h, 以92%的产率得到2-已烯醛

    名称:
    Tin(II) chloride dihydrate: A mild and efficient reagent for cleaving acetals.
    摘要:
    Tin(II) chloride dihydrate (SnCl2.2H2O) efficiently converts conjugated dioxolanes, and both dimethoxy and diethoxy acetals to aldehydes (84-98%). Similarly, nonconjugated dimethoxy and diethoxy acetals are also efficiently converted to aldehydes (84-94%). Conjugated pyrans and nonconjugated dioxolanes, however, are only converted to aldehydes in 17-38% yields.

    摘要:
    研究了乙酰化,α-溴化,亲核性苯硒基化,氧化消除/水解作为醛类α,β-脱氢的新方法。用溴在二氯甲烷中的乙缩醛处理得到相应的α-溴缩醛,产率为80-90%。然后,通过用由二苯基二硒化物,肼和碳酸钾在二甲基亚砜中原位生成的苯硒酸酯处理,可以方便地实现亲核性苯基硒烯基化。无支链的α-溴缩醛可干净地提供取代产物,而β和γ支链的则通过形式上的溴化氢损失而产生大量的α,β-不饱和缩醛。这些混合物的氧化消除/水解以50-80%的总产率提供α,β-不饱和醛。在叔α-溴缩醛的情况下,用苯硒烯酸酯处理仅得到作为异构体混合物的脱氢溴化产物。发现至少催化量的有机硒试剂的存在对于烯烃形成至关重要。提出了一种SET机制,包括苯硒酸酯诱导的电子转移到卤化物,溴离子的损失以及氢原子或质子/电子,用于苯甲酸酯促进的消除反应。旨在在分子内环化或开环反应中捕获以碳为中心的自由基的实验未能提供任何自由基中间体的证据。发现至少催化

    DOI:10.1016/s0040-4039(00)80396-2
    日期:1988.1
    Novel method for transforming aldehydes and acetals into 1,3-dithianes has been achieved with the aid of organotin thioalkoxides and organotin triflates. Under these reaction conditions, various acid-sensitive groups are tolerated. Differentiation between aromatic or aliphatic aldehydes and acetals has been realized.
