摘要: The carbon-nitrogen double bond can be conveniently reduced by reaction of the appropriate organic (or organometallic) compound with a mixture of triiron dodecacarbonyl [Fe3(CO)12] and methanol in benzene.DOI: 10.1021/jo00797a056 被引量: 23 ...
These reactions are proceeding by rate-determining nucleophilic attack by the alkoxide ion on the carbon–nitrogen double bond (AN# + DN). The restricted stereochemistry of the tetrahedral intermediates suggests that the E-hydroximoyl bromide and chloride may be undergoing unassisted ionization to ...

The aligned CNTs vary from 10 to 80 nm in diameter and because the CN bond length is shorter than CC, the result is the curving of basal planes forming the bamboo-like structure after nitrogen doping in the CNTs. The impedance value of CNTs is higher than that of HN-CNTs, as shown ...
Various Schiff bases have been prepared to study base induced carbon-nitrogen double bond migrations. Schiff bases derived from aliphatic aldehydes display highest selectivity. Hydrolysis of the resulting rearranged Schiff base provides an entry to make amines from aldehydes. The reaction has possible pra...
2-difunctionalization of C–C double bonds with two different nucleophilic agents in the absence of transition metal catalysts. Mild reaction conditions allowed the utilization of various functional groups and substitution patterns on amine nitrogen atom, providing diverse set of homo- and hetero...
