Usage

General Description

Cyclopropane is a colorless, flammable gas with a faint ether-like odor. It is a highly reactive compound due to the strain of the three carbon atoms in its cyclopropane ring, and it is used primarily as a medical anesthetic. Its high reactivity also makes it explosive and prone to reacting with other chemicals. Cyclopropane is no longer commonly used as an anesthetic due to its flammability and potential for causing explosions, as well as its tendency to cause post-operative nausea and vomiting in patients. However, it is still used in some specialized medical procedures, such as eye surgery, and it is also a precursor for the production of other compounds.

Nickel-Catalyzed Cyclopropanation with NMe4OTf and nBuLi

Nickel was identified as a catalyst for the cyclopropanation of unactivated olefins by using in situ generated lithiomethyl trimethylammonium triflate as a methylene donor. A mechanistic hypothesis is proposed in which the generation of a reactive nickel carbene explains several interesting observations. Additionally, our findings shed light on a report by Franzen and Wittig published in 1960 that had been retracted later owing to irreproducibility, and provide a rational basis for the systematic development of the reaction for preparative purposes as an alternative to diazomethane or Simmons-Smith conditions.

GASEOUS DIELECTRICS WITH LOW GLOBAL WARMING POTENTIALS

A dielectric gaseous compound which exhibits the following properties: a boiling point in the range between about ?20° C. to about ?273° C.; non-ozone depleting; a GWP less than about 22,200; chemical stability, as measured by a negative standard enthalpy of formation (dHf0); a toxicity level such that when the dielectric gas leaks, the effective diluted concentration does not exceed its PEL; and a dielectric strength greater than air.
