摘要:The Rhodium-Catalyzed Cyclization Of A Series Of 2,2-Diarylalkanoic Acids In The Presence Of Copper Acetate As An Oxidant Smoothly Proceeded Through Double C-H Bond Cleavages And Subsequent Decarboxylation To Produce The Corresponding Fluorene Derivatives. The Direct Cyclization Of Triarylmethanols Also Took Place Efficiently By Using An Iridium Catalyst In Place Of The Rhodium,While The Hydroxy Function Was Still Intact.

摘要:The present disclosure relates generally to the field of synthetic organic chemistry. More specifically, the disclosure is directed to a continuous flow process for synthesis of azides from alcohols and peroxides, wherein the process comprises azidation with trimethylsilyl azide and a catalyst Amberlyst-15. It is a non-hazardous, mild and controlled reaction giving good yields of azides. The azides can be further employed for synthesis of medicinally and industrially useful chemicals.

摘要:Methods for preparation of olefins, including 8- and 11-unsaturated monoenes and polyenes, via transition metathesis-based synthetic routes are described. Metathesis reactions in the methods are catalyzed by transition metal catalysts including tungsten-, molybdenum-, and ruthenium-based catalysts. The olefins include insect pheromones useful in a number of agricultural applications.

摘要:The invention relates to an organic polyspiralgrid nanopolymer material and a preparation method thereof, and belongs to the field of nanotechnology and organic electronics. The structure of the organic polyspiralgrid nanopolymer material is composed of grids containing a spiro ring that serves as a repeat unit to form a special nano polymer, and the structure shares the spiro ring structure. A synthetic method thereof relates to a synthon containing the spiro ring, and by means of a Friedel-Crafts reaction, an organic spirogrid and a nano polymer thereof are built. By means of reasonable molecular design and the Friedel-Crafts reaction with the advantages of being mild in reaction condition, high in yield, high in selectivity, simple in posttreatment, green, free of toxicity and the like, the problems that a traditional polymer molecule is complex in synthesis step, toxic in posttreatment, large in pollution and the like are solved.
