, p. 1734 - 1740 (2007/10/02)
Thermolysis of bromo(trimethylsilyl)methyltrimethylsilylmethyl 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 cycloaddtions is discussed.Keywords---thiocarbonyl ylide; 1,3-cycloaddition; organosilicon compound; thermolysis; tetrahydrothiophene; regioselectivity

, p. 4039 - 4042 (2007/10/02)
A novel and general method for generation of thiocarbonyl ylide by release of disiloxane from bis(trimethylsilylmethyl) sulfoxide (1) has been found.This method was also demonstrated for generation of aliphatic and aromatic thioaldehyde S-methylide.
NEW GENERATION OF THIOCARBONYL YLIDE AND ITS 1,3-CYCLOADDITION LEADING TO TETRAHYDROTHIOPHENE DERIVATIVES

, p. 3011 - 3014 (2007/10/02)
Thiocarbonyl ylide was found to be generated by thermolysis of bromo(trimethylsilylmethylthio)methyltrimethylsilane and its 1,3-cycloaddition provided a new method for synthesis of tetrahydrothiophenes.
