A number of 1- and 1,2-disubstituted cyclopropenes undergo [4+2]- cycloaddition to methyl vinyl ketone or acrolein at ambient temperature to produce 2-oxabicyclo[4.1.0]hept-3-enes. When 1-phenyl-2- trimethylsilylcyclopropene is treated with 0.4 mol. equiv. of m- chloroperbenzoic acid, the derived ring-opened enone undergoes [4+2]- cycloaddition to the remaining starting material at ambient temperature.

Sila-morita-baylis-hillman reaction of Arylvinyl ketones: Overcoming the dimerization problem

supporting information; experimental part, p. 253 - 255 (2009/06/28)
Arylvinyl ketones, under Morita-Baylis-Hillman (MBH) reaction conditions, produce a mixture of dimerization products. We propose a solution to this problem: a sila-MBH reaction. This cascade reaction involves addition of phosphine catalyst to arylvinyl ke
Oxidation of Alcohols with Dimethyl Selenide -N-Chlorosuccinimide Complex
Takaki, Ken,Yasumura, Masateru,Negoro, Kenji
, p. 54 - 57 (2007/10/02)
Dimethyl selenide reacts with N-chlorosuccinimide (NCS) to give a new complex, with which various alcohols are successfully oxidized to carbonyl compounds.Notably, this method is applicable to allylic alcohols without formation of allylic chlorides and rearranged products. β-Hydroxy selenide 8 is converted to β-oxo selenide 9 by treatment with NCS.On the other hand, facile deselenization occurs in the case of γ-hydroxy selenide 10 under similar conditions.A plausible mechanism of the reactions is also discussed.
