The invention relates to a compound of the general formula (I) NOS&#x2014;Ar-L-Ar'&#x2014;SON, wherein: &#x2014;Ar and Ar&#x2032; are aromatic building blocks; and &#x2014;L is a linking group comprising at least one heteroatom as well as an organic chain denoted as Sp&#x2033; and having at least two carbon atoms. The invention also relates to a compound of the general formula (II) wherein: &#x2014;Ar and Ar&#x2032; are aromatic building blocks; &#x2014;L is a covalent bond or a linking group; &#x2014;m and n are both 0 or 1, at least one of m and n being 1; &#x2014;Sp and Sp&#x2032; are organic chains having at least two carbon atoms. The invention also relates to the use of these compounds as cross linking agents in the manufacture of polymers.

Non explosive bis-sulfonyl azides

This application relates to a process for making a pharmaceutically acceptable formulation of gadofosveset trisodium monohydrate, wherein the process uses no more than one chromatographic purification for removal of impurities.

Process for manufacture of gadofosveset trisodium monohydrate

The object of the present invention is the use of phosphonium salts in coupling reactions, and a method for their preparation.

Use of phosphonium salts in coupling reactions and process for their manufacture

A color photographic silver halide material having a support, which material comprises at last one blue-sensitive, yellow-coupling silver halide emulsion layer and at least one green-sensitive, magenta-coupling silver halide emulsion layer and at least one red-sensitive, cyan-coupling silver halide emulsion layer, and which contains at least one masking coupler which has two chromophores which absorb in the wavelength range from 420 to 750 nm and are eliminable or decolorizable by coupling with the developer oxidation product, is distinguished by improved sensitivity associated with undiminished color purity.

Color photographic silver halide material

A color photographic silver halide material, which has a support which comprises at least one blue-sensitive, yellow-coupling silver halide emulsion layer nearest the light source and at least one green-sensitive, magenta-coupling silver halide emulsion layer and at least one red-sensitive, cyan-coupling silver halide emulsion layer which are further from the light source than is the at least one blue-sensitive layer, and which contains at least one cyan masking coupler which has its maximum absorption above 650 mn, the red-sensitive layers have their maximum sensitivity at 620&plusmn;20 nm and the absorption of the masking coupler at the maximum sensitivity of the red-sensitive layers is at most 70% of its absorption at 690 mn, is distinguished by improved color reproduction and color saturation in the magenta layer without loss of sensitivity.
