Description The cleavage of styrene oxide by different reagents like Raney nickel, palladium–carbon and sodium borohydride in the presence of b-cyclodextrin and its derivatives like b-CD-epichlorohydrin b-CD-polymer and heptakis-2,6-di-O-methyl-b-cyclodextrin DM b-CD showed distribution in formation of ethylbenzene, 1-phenylethanol and 2-phenylethanol. Formation of deoxygenated products like styrene and ethylbenzene were suppressed by b-CD and its derivatives under hydrogenation over Raney nickel favouring increase in proportion of 2-phenylethanol. b-CD and its derivatives regulated increase in formation of 1-phenylethanol under reduction by Pd–C and NaBH . Observed selectivities have been correlated 4 to arise directly from the disposition adopted by styrene oxide inside the b-CD cavity, the nature and manner of which has been arrived at from the spectroscopic studies UV and NMR of inclusion.
