Preparation of Sterically Congested Di(4-pyridyl)diazomethanes and Characterization of Triplet Carbenes from Them
摘要:
Di(4-pyridyl)diazomethanes having two and four ortho chlorine groups were prepared, and the triplet carbenes generated from them were characterized by ESR and UV/vis at low temperature and time-resolved UV/vis at room temperature. An appreciable increase in the stability of triplet carbenes is achieved by introducing ortho chlorine groups.
