Abstract

The reaction of the anilines RNH2 [R = C6H4(o-CN), C6H4(p-CN), C6H4(m-CN), C6H4(o-C6H5), C6F5 and C6H4(o-CF3)] with Ph2PCl and inorganic or organic bases in differing stoichiometry and in different solvents has been studied. The electronic properties and steric effects of the substituent groups, the base employed, the stoichiometry and the solvent all influence the outcome of the reaction and a series of aminophosphines, diphosphinoamines and iminobiphosphines have been isolated and characterised. The structures of three diphosphinoamines and three iminobiphosphines have been established using single-crystal X-ray diffraction.

Functional group

In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. This enables systematic prediction of chemical reactions and behavior of chemical compounds and the design of chemical synthesis. The reactivity of a functional group can be modified by other functional groups nearby.

Substituent

In organic chemistry, a substituent is one or a group of atoms that replaces (one or more) atoms, thereby becoming a moiety in the resultant (new) molecule. (in organic chemistry and biochemistry, the terms substituent and functional group, as well as side chain and pendant group, are used almost interchangeably to describe those branches from the parent structure, though certain distinctions are made in polymer chemistry. In polymers, side chains extend from the backbone structure.

Aryl group

In organic chemistry, an aryl is any functional group or substituent derived from an aromatic ring, usually an aromatic hydrocarbon, such as phenyl and naphthyl. "Aryl" is used for the sake of abbreviation or generalization, and "Ar" is used as a placeholder for the aryl group in chemical structure diagrams, analogous to “R” used for any organic substituent. “Ar” is not to be confused with the elemental symbol for argon. A simple aryl group is phenyl (), a group derived from benzene.
