CHEMOSELECTIVE REACTIONS OF ULTRASONICALLY DISPERSED POTASSIUM WITH SOME BROMINATED HYDROTHIOPHENE S,S-DIOXIDES
The reactions of ultrasonically dispersed potassium (UDP) with 4-bromo-2-sulfolenes resulted in chemoselective deprotonation at the C-5 position leading to the elimination-dimerization products.The possible C-S bond and C-Br cleavage reactions were not detected.The reaction of UDP with 3,4-dibromosulfolane resulted in dehydrobromination and double dehydrobromination.
