It has been found that textile materials, for example vegetable and animal fibers (cotton, artificial silk from regenerated cellulose, wool and silk) can be printed with water-soluble acyl derivatives
In the presence of a catalytic amount of NaOH, the selective N-alkylation of various heteroaromatic primary amines is reported. With 1 equiv of NaOH, N1,C5-dialkylation of 4-phenyl-2-aminothiazoles has been investigated. Reaction of in situ generated aldehyde with amine yields the N-alkylated...

New chelating 伪-aminophosphanes were obtained by Mannich-type reactions between formaldehyde, bis(2-methoxyphenyl)phosphane and aliphatic primary diamines bearing either a C2 or C3 carbon bridge between the amine functionalities. The reaction conditions, and in particular, the reaction sequence was ...
