The year 2002 witnessed a wide range of interesting developments in Group 15 chemistry, with highlights including the first experimental observation of tetranitrogen, N4,1and the synthesis of the first non-carbon-containing metallocene, [Ti(η5-P5)2]2−(vide infra).2Nitrogen and phosphorus compounds continue to be used extensively as ligands, with the development of asymmetric phosphine-based catalysts described in the Nobel Lectures of Knowles3and Noyori.4However, due to space limitations, the use of Group 15 based ligands is beyond the scope of this report, and only transformations of the ligands themselves are included. The summaries of each piece of work cited are as concise as possible in order to maximise the range of chemistry described.
