The reactions of the zwitterionic species 1 with ortho -substituted aryl isocyanates proceed in an unusual way, resulting in the formation of the P-containing carbamates 3. In the latter (except for X=F) the CH 2 P protons are anisochronous and give

Pyridinium and isoquinolinium ylides (7 and 12) derived from malonic ester react in an unusual manner with isocyanates giving the new pyridinium ylide (9) and the new isoquinolinium ylide (14). C N Migration of the COOEt group takes place at room tem

Reactions between isocyanates, carbanions with an acetyl group at the carbanion center occurvia rearrangement of the intermediate N-anions into isomeric C-anions by C→N-migration of the MeC(O)group. The acetyl group undergoes migration easier than
