chlorochromate (2,6- DCPCC ) was found to be an efficient reagent for the conversion of acetals, thioacetals, and 1,1-diacetates to their corresponding carbonyl compounds under neutral and anhydrous conditions in good to excellent yields. Selective deprotection of acetals or 1,1-diacetates in the presence of thioacetals at room temperature is also observed with this reagent.
发现2,6-二 羧基吡啶鎓氯铬酸盐(2,6- DCPCC )是一种在中性和无水条件下以良好或优异的收率将乙缩醛,硫缩醛和1,1-二乙酸酯转化为相应的羰基化合物的有效试剂。用该试剂在室温下也观察到在乙缩醛存在下乙缩醛或1,1-二乙酸酯的选择性脱保护。
