| Abstract: | Use of sterically congested 1,4-diazabutadienes as dipols in reactions with some heterocumulenes has been investigated. A synchronous concerted. mechanism has been considered. The hydantoine-type structure of products has been discussed with respect to their chemical and spectral behaviour.Part XII:Moskal J., Milart P., J. Chem. Res., in press. |
