New organotungsten reagents bearing a N-succinimidyl or N-sulfosuccini
midyl ester function have been prepared, specifically coupled with ami
nes, amino acids and proteins and provide a promising basis for the pr
eparation of heavy metal labelling agents designed for X-ray structura
l analysis of biological systems.
