Abstract
Water has been found for the first time as a useful solvent in the WillgerodtKindler WK reaction for the synthesis of benzothiomorpholides in high yield at 80°C for 3 h This novel approach confronts the WK protocol with a new situation in which water not only is not regarded as a serious disadvantage but also is applied in this case as a useful solvent in the reaction The basis of this finding is the presence of a methylene chain in the carbonyl substrates which leads to the high reaction selectivity of benzaldehydes over acetophenones
