Exempel på hur man kan använda CYCLOPROPANES i en mening

• These can be reduced to cyclopropanes or hydrolysed to give cyclopropanones by a geminal halide hydrolysis.
• The Johnson–Corey–Chaykovsky reaction (sometimes referred to as the Corey–Chaykovsky reaction or CCR) is a chemical reaction used in organic chemistry for the synthesis of epoxides, aziridines, and cyclopropanes.
• However, the high ring strain present in cyclopropanes makes them challenging to produce and generally requires the use of highly reactive species, such as carbenes, ylids and carbanions.
• Although not formally arenes, tricyclopropylbismuth(III) reagents react with aryl halides and triflates under Pd(0) catalysis in a similar fashion to afford a variety of aryl and heteroaryl cyclopropanes:.
• In 1912, Kischner later applied the catalytic decomposition to pyrazoline bases and developed a versatile method for the preparation of substituted cyclopropanes by thermal decomposition of pyrazolines.
• The group focuses on the research areas of Aryne chemistry, asymmetric catalysis, donor-acceptor cyclopropanes and N-heterocyclic carbene organocatalysis.
