    Can polymerization trap intermediates in 1,3-dipolar cycloadditions?
    摘要:
    2,2,4,4-Tetramethyl-3-thioxocyclobutanone S-methylide (TTCM) is a nucleophilic 1,3-dipole which is known to undergo two-step cycloadditions to very electron poor olefins. When this 1,3-dipole is generated from its precursor, the 1,3,4-thiadiazoline 7, in acrylonitrile or acrylic esters at 45-degrees-C, only cycloaddition and no polymerization is observed, suggesting a concerted cycloaddition. Small amounts of polymers were observed alongside the cycloadducts with nitroethylene, methacrylonitrile, and methacrylates. Most cycloadducts were produced as regioisomeric mixtures. The reaction of TTCM with benzylidenemalononitrile, a nonpolymerizable olefin, is nonconcerted and furnished in THF and 1 vol % methanol or 3 vol % water a 7-membered lactim methyl ether or lactam formed by interception of a ketene imine. The observed polymerizations are radical in nature and are proposed to be initiated by a minor contribution of a diradical intermediate to the cycloaddition reaction.

  • Thio- and Dithioesters as Dipolarophiles in Reactions with Thiocarbonyl Ylides

Dialkyl phosphonodithioformates 8 are shown to be efficient C=S dipolarophiles in reactions with thiocarbonyl S-methylides 3a–3d, affording 1,3-dithiolane-4-phosphonates.

  • Cycloadditions of two thiocarbonyl ylides with α,β-unsaturated esters and nitriles: steric course and mechanism

    日期:2002.1
    In the probably concerted cycloadditions of the sterically hindered thiocarbonyl ylide 1 with fumaronitrile, maleonitrile, and dimethyl fumarate, the dipolarophile configuration is retained whereas retention/inversion 99:1 for dimethyl maleate (51 times less reactive than fumarate) signals a small involvement of a two-step pathway. The latter becomes dominant when two acceptor groups stabilize the

  • Strong influence of the trifluoromethyl group on the chemoselectivity of [3+2]-cycloadditions of thiocarbonyl S -methanides with α,β-unsaturated ketones

    situ-generated reactive thiocarbonyl S-methanides were reacted with fluorinated enones. The type of the obtained [3+2]-cycloadduct depends strongly on the location of the activating CF3 group. In the case of enones containing the CF3CHCH moiety, the [3+2]-cycloaddition occurs chemo- and regioselectively onto the CC bond to give trifluoromethylated tetrahydrothiophene derivatives. On the other hand, enones containing
