Abstract
A sandwich zwitterionic ruthenium
complex (<b>4</b>) was prepared by an intramolecular 1,3-dipolar
cycloaddition of the ruthenium azido isocyanide [CpMe<sub>5</sub>Ru(CNAr)<sub>2</sub>N<sub>3</sub>] (<b>2</b>). The reaction involved a formal
1,3-migration mechanism along a highly conjugated system linking to
a cyanamido group
