Abstract
Fragmentation of the (R)-(+)-1-phenyl-1-propanol radical cation ([(BZC2H5)R]+) is markedly affected by asym. micro-solvation. The C.alpha.-C.beta. bond cleavage in the heterochiral [(BZC2H5)R.bul.BDSS]+ cluster is more efficient than in the homochiral [(BZC2H5)R.bul.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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
