Three-membered rings, with two hetero atoms

Three-Membered Rings with Two Hetero Atoms Ernst Schmitz... [Pg.487]

Thus it is not surprising that three-membered rings with two hetero atoms were mentioned in the literature at an early stage. For example, at the turn of the century, nitrones, hydrazones, and aliphatic diazo compounds were all formulated with three-membered rings (I, 2, 3). Later the three-membered ring structures for these compounds became questionable. The structure of the aliphatic diazo compounds was studied very intensively. For diazomethane no clas-... [Pg.83]

In the last 10 years many three-membered rings with two hetero atoms have been synthesized. Their formation occurs surprisingly smoothly with an ease comparable to that of the three-membered rings with one hetero atom. The oxaziranes (I), diaziridines (2), and diazirincs (3) have become, in a very short time, classes of compounds with an extensive literature. [Pg.85]
