Triarylmethyl radicals and the use of inert carbon free radicals in MRI

A radical compound of formula Ia wherein: each Ar12, which may be the same or different, represents a 6-membered carbocyclic, at least one group Ar12 being a group Ar1 ; each group Ar1 represents a 6-membered ring optionally substituted at the or any ortho carbon by a group R1, R2, R3 or R4, at the or any meta carbon by a group R2 or R3, and at any para carbon by a group R1, R2, R3 or R4, with the proviso that no more than two ring carbons are unsubstituted; each of R1, R2, R3 or R4, which may be the same or different, independently represents a group of formula --M, --XM, --XAr2 or --Ar2 ; M represents a water solubilizing group, each group X, which may be the same or different, represents an oxygen or sulphur atom or a NH or CH2 group.

Organo-metal compositions, preparation and use

Complexes of a transition metal and a tetrasubstituted aromatic compound which contain at least two transition metal atoms. At least two of the substituents are -SH groups, the other two substituents being -SH, -OH and -NHR. The complexes are prepared by reacting the tetrasubstituted aromatic compound with a transition metal compound in the presence of a disubstituted aromatic compound. Depending on the relative proportions of the di- and tetra--substituted compounds, the resulting complex may contain more than one residue from the tetra-substituted compound and more than two transition metal atoms. The complexes possess infra-red absorbing properties which vary in dependence on the particular complex, the complexes with more than one residue from the tetrasubstituted compound absorbing radiation of longer wavelength. The compounds can be used to provide infra-red absorbing compositions, for example as a coating or inter-layer for glass. The complexes may be used together with one or more different infra-red absorbing materials. The tetra-substituted aromatic compound may be a tetra-thiol and this can be prepared from an aromatic compound containing at least four halogen substituents by reaction with an alkaline thiol compound in the presence of iron and sulphur in a polar solvent such as dimethyl formamide.
