Rutjes, Floris P. J. T. published the artcileCyclic 1,2-dinitrogen compounds through N,N’-bis(methoxycarbonyl)hydrazinium intermediates, Product Details of C7H13BrSi, the publication is Tetrahedron Letters (1988), 29(52), 6975-8, database is CAplus.
Acid-catalyzed cyclization of methoxymethyl-substituted acyclic hydrazides provides cyclic hydrazides in moderate to good yields. E.g., MeOCH2[N(CO2Me)]2(CH2)nCH:CH2 (n = 1-3) were treated with TiCl4 in CH2Cl2 to give 32, 80, and 15% cyclic hydrazides I (same n), resp. A mechanism involving bis(methoxycarbonyl)hydrazinium intermediates is presented.
