  摘要：

  The (E)-1-(arylsulfonyl)-4-(trimethylsilyl)-1-butenes 9, 25, and 26 are prepared by CuCl2-promoted and by photolytic additions of their precursor l-arylsulfonyl chlorides and bromides to 4-(trimethylsilyl)-1-butene (14) and then dehydrohalogenation of the resulting 1-(arylsulfonyl)-2-halo-4-(trimethylsilyl)butanes 15a, 15b, 23a, and 23b with KOH, LDA, or n-BuLi. Silylbutene 14 is obtained from reaction of [(trimethylsilyl)methyl]magnesium chloride (16, X = Cl) and allyl bromide (17) and better by protiodesilylations of (E)- and (Z)-1,4-bis(trimethylsilyl)-2-butenes (20) with sulfuric or trifluoroacetic acids. (Arylsulfonyl)(trimethylsilyl)-1-butenes 9, 25, and 26 are converted efficiently by LDA or n-BuLi at -78 degrees C to 1-(arylsulfonyl)-1-lithio-4-(trimethylsilyl)-1-butenes 10, 27a, and 27b, respectively. Reactions of 27a and 27b with deuterium oxide yield (E)-1-(4-chlorophenylsulfonyl)-1-deuterio-4-(trimethylsilyl)-1-butene (28a, 83%) and (E)-1-deuterio-1-(4-methylphenylsulfonyl)-4-(trimethylsilyl) 1-butene(28b, 89%), respectively. 1-Lithio derivatives 10, 27a, and 27b undergo benzylations by benzyl bromide in THF/HMPA with retention of the positions of their olefinic double bonds to give the (E)-2-(arylsulfonyl)-1-phenyl-5-(trimethylsilyl)-2-pentenes 29a, 29b, and 29c, respectively, in 84-90% yields. Of particular interest is that asa-care isomerized to their corresponding 2-(arylsulfonyl)-1-phenyl-5-(trimethylsilyl)-3-pentenes 30a-c, respectively, which then undergo conjugative eliminations df their arylsulfonyl and their trimethylsilyl groups to give (E)-5-phenyl-1,3-pentadiene (33) in 56-63% yields upon reactions with TBAF in THF at 25 degrees C. Further, 27b reacts with 1,3-dichloropropane to form 1-chloro-4-(4-methylphenylsulfonyl)-7-(trimethylsilyl)-4-heptene (35) which is cyclized by n-BuLi to 1-(4-methylphenylsulfonyl)-l-(3-(trimethylsilyl)-1-propenyl) (37, 67%). Elimination of 37 by TBAF then gives allylenecyclobutane (34, n = 3, 84%) simply. This study thus reveals that 8, 25, and 26 have outstanding potential as 1-(1,3-butadienyl) anion (7) and 1,1-(1,3-butadienyl) dianion (8) synthons.
