Deprotonation of the alkoxysulphone (5) followed by quenching with diphenyl disulphide yields the dithioorthoester (6) and not the expected ketene monothioacetal (7). Attempts at orthoester exchange of (6) with decanol with a variety of reagents lead to ring opened products. Quenching of the anion derived from (5) with sulphuryl chloride or bromine leads respectively to the chloride (19) and bromide
烷氧基砜的去质子化反应(5),然后用二苯基二硫化物淬灭,得到二硫代原酸酯(6),而不是预期的乙烯酮单硫缩醛(7)。尝试与癸醇和多种试剂进行原酸酯(6)交换会导致开环产物。用硫磺酰氯或溴对衍生自(5)的阴离子进行淬灭分别导致了氯离子(19)和溴离子(20)。这些卤化物的溶剂分解导致形成亚磺酸酯。
