heterogeneous catalysts and therefore they can be selective,
reactive and recyclable. With the host effects of b-CD and
superparamagnetism of iron oxide, MNPs-bCD are expected
to have higher potential applications in substitution reactions
of benzyl halides. In conclusion, this method offers several
advantages including easy way to operate, short reaction
times, clean reaction profiles, high isolated yields, safe and
cost-effective procedure for the preparation of benzyl thio-
cyanates and azides, which make it a useful and attractive
process to synthesis of benzyl thiocyanates and azides.
