Carbonyl manganese complexes with chelating or bridging mesoionic di(1,2,3-triazolylidene) ligands were efficiently synthesised and fully characterised, including the X-ray diffraction study of a bimetallic manganese(0) complex. This unprecedented bimetallic complex displayed high yield and selectivity in the catalytic oxidation of secondary alcohols and benzyl alcohol with tert-butyl hydroperoxide under mild conditions.

Paragraph 0035; 0036, (2020/04/17)
The invention provides a preparation method of 1-chloro-1-chloroacetyl cyclopropane. The preparation method comprises the following steps: 1)reacting 1, 3-butadiene with diazomethane to generate vinylcyclopropane; 2)reacting the vinyl cyclopropane with an oxidation reagent to generate acetyl cyclopropane; and 3)reacting the acetyl cyclopropane with a chlorination reagent to generate the target product 1-chloro-1-chloroacetyl cyclopropane. The method can reduce the use of strong acids, strong bases and chlorination reagents in the preparation of the 1-chloro-1-chloroacetyl cyclopropane, thereby reducing the discharge of three wastes and lowering the safety risk, and can enhance the synthesis yield to adapt to industrial production.
