Abstract
2-Lithio-1,3-dithianeand2-lithio-2-trimethylsilyl-l,3-dithianereactwithnitrilestoaffordprimaryaminoketene dithioacetals in good yields; these compounds exhibit marked ambident nucleophilicity. Use of other carboxylic acid derivatives as electrophiles normally produces acyl dithianes, however 2-lithio-2-trimethylsilyl-1,3-dithiane reacts with benzoyl cyanide to give a cyanoketene dithioacetal.
