2-Vinyl-1,1,2-trihalocyclopropanes - Valuable five carbon cyclopropane and cyclopropene synthetic intermediates

The dichloro- and dibromocarbene adducts of chloroprene and 2,3-dichlorobutadiene are readily dehalogenated by reaction with methyllithium to give 1-halo-2-vinylcyclopropenes which on further lithium-halogen exchange give synthetically useful 1-lithio-2-vinylcyclopropenes. Trapping of 1-lithio-2-(1-chlorovinyl)cyclopropene with methyl chloroformate leads to a very unusual cyclononadienyne.

Efficient and stereoselective nitration of mono- and disubstituted olefins with AgNO2 and TEMPO

Nitroolefin is a common and versatile reagent. Its synthesis from olefin is generally limited by the formation of mixture of cis and trans compounds. Here we report that silver nitrite (AgNO2) along with TEMPO can promote the regio- and stereoselective nitration of a broad range of olefins. This work discloses a new and efficient approach wherein starting from olefin, nitroalkane radical formation and subsequent transformations lead to the desired nitroolefin in a stereoselective manner.

Molecular Fingerprints With Enhanced Identifying Capability, Method for Preparing Same and Use Thereof

The invention concerns a method for preparing a molecular fingerprint comprising sites for identifying at least one target molecule, said fingerprint being obtained from at least one master molecule of polymeric type, called master polymer. The invention is characterized in that said master polymer is different from the target molecule(s), and is capable of being eliminated by degradation and/or washing, and that at least 5% in number of monomer units constituting the master polymer are involved in the formation of the sites for identifying the target molecule(s).

Phosphepines: Convenient access to phosphinidene complexes

Reaction of o-diethynylbenzene with transition metal-complexed primary phosphines gives in a single base-induced step stable phosphepine complexes as confirmed by X-ray data. At 75-80 °C these phosphepines undergo clean cheletropic elimination of naphthalene to give transient carbene-like phosphinidene complexes that can be trapped in high yield by alkenes, alkynes, and alcohols.
