OXO-NITROGENATED IRON COMPLEX, CATALYTIC SYSTEM COMPRISING SAID OXO-NITROGENATED IRON COMPLEX AND PROCESS FOR THE (CO)POLYMERIZATION OF CONJUGATED DIENES

Oxo-nitrogenated iron complex having general formula (I): in which: R1 and R2, identical or different, represent a hydrogen atom; or they are selected from linear or branched, optionally halogenated C1 - C20, pr

Cross-coupling of phenyl halides with sodium dicyanomethanide in the presence of Tetrakis(triphenyphosphine)palladium

1-Aromatic substituted imidazoles were synthesized by a convenient modified process. A cross-coupling reaction of phenyl halides with sodium dicyanomethanide has been achieved to produce the arylmalononitriles coupling products as zwitterionic precursors

Synthesis and Diels - Alder cycloadditions of exo-imidazolidin-2-one dienes

(Figure presented) An efficient and versatile synthesis of novel exo-imidazolidin-2-one dienes is described. This involves the base-assisted condensation/cyclization cascade reaction of the monoimino derivatives of diacetyl with a series of isocyanates. This methodology enables preparation of symmetrical dienes, as long as the substrates have the same N substituent. Moreover, use of different N-substituted starting materials leads to formation of nonsymmetrical dienes. The reactivity of these dienes was evaluated in Diels - Alder reactions, showing a high reactivity.

SYNTHESIS AND REACTIONS OF TRIPHENYLARSINIMINES

Triphenylarsinimines formed in situ from isocyanates and triphenylarsine oxide have been found to react smoothly with carbonyl compounds like aldehydes, quinones and aromatic ketones giving the corresponding Schiff's bases in high yields.In the case of aldehydes, quinones or activated ketones, e.g., α-diketones, only a catalytic amount of triphenylarsine oxide is necessary for the reaction to proceed to completion.Quinones react with particular ease.Thus the previously unknown 9,10-phenanthrenequinone N-phenylimine 12 (R = Ph, Scheme IV) can be prepared in high yield from 9,10-phenanthrenequinone and phenyl isocyanate under catalytic influence of triphenylarsine oxide.Orthoquinones like 9,10-phenanthrenequinone react with vinylic isocyanates, forming monoimines 13 which rearrange to 1,4-oxazines 14 (Scheme V).Diisocyanates react under the catalytic action of triphenylarsine oxide with dialdehydes under mild conditions, forming some interesting new polymers 25, 26 in high yields.Reactions with aliphatic isocyanates give N-alkyl-N'-arylcarbodiimides, whereas reactions with isothiocyanates proceed through intermediates 20 and 21 to mixed carbodiimides 16, 24 and 25.
