（R）-（+）-1-苯基-1-丙醇自由基阳离子（[（BZC 2 H5）R]+）的断裂受到不对称微溶剂化的显著影响（见图片）。异手性[（BZC 2 H5）R.BDSS]+簇合物中Cl ±-Cl ²键的断裂比同手性[（BZC 2 H5）R.BDRR]+簇合物中Cl ±-Cl ²键的断裂更有效。这种差异归因于结构因素，使BDSS在与[（BZC 2 H5）R]+的加合物中成为比BDRR更好的氢键受体。BZ = PhCHOH，BD = 2，3-丁二醇。
Fragmentation of the (R)-(+)-1-phenyl-1-propanol radical cation ([(BZC 2H5)R]+) is markedly affected by asymmetric microsolvation (see picture). The CI±-C I² bond cleavage in the heterochiral [ (BZC2H 5)R.BDSS]+ cluster is more efficient than in the homochiral [(BZC2H5) R.BDRR]+. The difference is ascribed to structural factors that make BDSS a better H-bond acceptor than BDRR in their adducts with [(BZC2H5) R]+. BZ = PhCHOH, BD = 2,3-butanediol.
