Reactions of diazonium salts with 4-substituted phenylaminopent-3-en-2-ones produce the corresponding 4-phenylimino-3-phenylhydrazonopentan-2-ones. On the other hand, the reaction of diazonium salt with 4-amino(or 4-methylamino)pent-3-en-2-one gives a mixture of two isomers approaching the tautomeri

We report a 1 H, 13 C and 15 N NMR investigation of one symmetrically substituted 2,7-dichloro and two unsymmetrically substituted 2-chloro and 4-bromo DMAN [1,8-bis(dimethylamino)naphthalene] proton sponges and their protonated salts. From a consideration of the NMR data reported we conclude, that

## Abstract ^13^C and ^15^N NMR chemical shifts were measured for __N__^1^‐alkyl‐__N__^2^‐arylthioureas. The absence of decoalescence of the __N__^1^‐alkyl group carbon signals down to 190 K, the europium‐induced chemical shifts and the molecular mechanics calculations indicate that the preferred c
