molecules such as dyes. This modification is usually performed as a final step, since sulfonated molecules are poorly soluble in most organic solvents, which complicates their synthesis and purification. This work compares the intrinsic lability of different sulfonate esters, identifying new sulfonate protecting groups and mild, selective cleavage conditions.

水溶性的能力而备受推崇。这种修饰通常作为最后一步进行,因为磺化分子在大多数有机溶剂中的溶解性很差,这使得它们的合成和纯化变得复杂。这项工作比较了不同
