  Halogenative Deoxygenation of Ketones; Vinyl Bromides and/orgem-Dibromides by Cleavage of 1,3-Benzodioxoles (Ketone Phenylene Acetals) with Boron Tribromide

  摘要：

  代表性的酮1类化合物通常在良好的产率下通过酮的二甲基缩酮与1,2-二羟基苯的反式缩醛化反应，并与三溴化硼裂解，转化为相应的1,3-苯并二噁烷5。由α-非支链脂肪酮衍生的1,3-苯并二噁烷通常生成乙烯基溴和偕二溴化合物的混合物；在大多数情况下，通过选择合适的反应时间可以有选择性地获得纯的偕二溴化合物。由α-支链酮衍生的1,3-苯并二噁烷产生复杂的混合物，其裂解似乎在合成上意义不大。芳香酮的1,3-苯并二噁烷仅生成乙烯基溴。脂肪族环状偕二溴化合物3通过相转移催化脱溴反应转化为相应的乙烯基溴2。

  Improved methods for generating a —C—C— bond by cross-coupling of a transferable group with an acceptor group. The transferable group is a substituent of an organosilicon nucleophile and the acceptor group is provided as an organic electrophile. The reaction is catalyzed by a Group 10 transition metal complex (e.g., Ni, Pt or Pd), particularly by a palladium complex. Certain methods of this invention use improved organosilicon nucleophiles which are readily prepared, can give high product yields and exhibit high stereo selectivity. Methods of this invention employ activating ions such as halides, hydroxide, hydride and silyloxides. In specific embodiments, organosilicon nucleophilic reagents of this invention include siloxanes, particularly cyclic siloxanes. The combination of the cross-coupling reactions of this invention with ring-closing metathesis, hydrosilylation and intramolecular hydrosilylation reactions provide useful synthetic strategies that have wide application.
