Thiocarbonyl Ylides VI. New Generation of Thiocarbonyl Ylides from Organosilicon Compounds Containing Sulfur and Their 1, 3-Cycloadditions

抄録

Thermolysis of bromo (trimethylsilyl) methyl trimethylsilylmethyl sulfide was found to give a thiocarbonyl ylide, the 1, 3-cycloaddition of which proved a new method for the synthesis of tetrahydrothiophenes. The effect of the silyl group of the ylide on the regio- and stereoselectivity in these 1, 3-dipolar cycloadditions is discussed.
