摘要

We report the preparation of terpyridine-like or genuine terpyridine ligands bearing appended nitronyl nitroxide (NIT) or imino nitroxide (IM) radicals. The synthetic protocol is based on multiple condensations between N, N′-dihydroxy-2, 3-diamino-2, 3- dimethylbutam and the corresponding aldehydes. Three of these radicals have been characterized by X-ray diffiaction on single crystals, from which the molecular structures ...
