In a facile procedure, 2-(1, 3-dithian-2-ylidene)-l-aryl ketones 1 vere reduced with magnesium in methanol to give α-aryl-β -(1, 3-dithane) alcohols 2 in good to high yields.
Allylic alcohols react with aryl iodides in the presence of tri-n-butylamine and a catalytic amount of a silica-bound bidentate sulfur palladium (0) complex to form 3-arylaldehydes or ketones in good yields.
Compressed CO2 could promote the disproportionation reactions of aryl alcohols in water medium significantly.The control experiments indicated that the effect of CO2 on the properties of the reactant/water emulsions w...Compressed CO2 could promote the disproportionation reactions of aryl alcohols in water medium significantly.The control experiments indicated that the effect of CO2 on the properties of the reactant/water emulsions was the main reason for the acceleration of the reactions rate.展开更多
