The article conveys some information:
We report a catalytic strategy that generates rhodium-carbynoids by selective diazo activation of designed carbyne sources. We found that rhodium-carbynoid species provoke C(sp2)-C(sp2) bond scission in alkenes by inserting a monovalent carbon unit between both sp2-hybridized carbons. This skeletal remodeling process accesses synthetically useful allyl cation intermediates that conduct to valuable allylic building blocks upon nucleophile attack. Our results rely on the formation of cyclopropyl-I(III) intermediates able to undergo electrocyclic ring-opening, following the Woodward-Hoffmann-DePuy rules.tert-Butyl carbamate(cas: 4248-19-5Application In Synthesis of tert-Butyl carbamate) was used in this study.
tert-Butyl carbamate(cas: 4248-19-5) belongs to anime. Reaction with nitrous acid (HNO2), which functions as an acylating agent that is a source of the nitrosyl group (―NO), converts aliphatic primary amines to nitrogen and mixtures of alkenes and alcohols corresponding to the alkyl group in a complex process. This reaction has been used for analytical determination of primary amino groups in a procedure known as the Van Slyke method.Application In Synthesis of tert-Butyl carbamate
