- Preparation method of N,N-dimethyl benzoate composite
-
The invention relates to a preparation method of an N,N-dimethyl benzoate composite, in particular to a preparation method for preparing N,N-dimethyl benzoate by using N,N-dimethylaniline, bi(trichloromethyl)carbonic ester and alcohol as raw materials. The raw materials are cheap and easy to obtain, the yield is high, a midbody does not need to be purified, a continuous reaction can be performed without replacing solvents, the preparation method is cheap, environmentally friendly, easy to implement and suitable for industrialization, and the method can be used for preparing the important chemical and medical midbody through N,N-dimethyl benzoyl chloride.

- Synthesis of a Cyclodextrin Heterodimer Having α- and β-Cyclodextrin Units and Its Cooperative and Site-Specific Binding
-
A cyclodextrin heterodimer, which has α- and β-cyclodextrin units as two different receptor sites, was prepared.It showed cooperative and site-specific binding to isoamyl p-dimethylaminobenzoate with the alkyl group included in the β-cyclodextrin cavity while dimethylaminobenzene moiety partially included in the α-cyclodextrin cavity.This binding mode was substantiated by the fact that the TICT emission of this guest is greatly enhanced by the cyclodextrin heterodimer.
