Reaction of arylmethylidene derivatives of malononitrile dimer with 1,3-cyclohexanediones in anhydrous methanol in the presence of sodium methylate as catalyst affords 4-amino-5-aryl-2-methoxy-6-oxo-5,6,7,8,9,10-hexahydrobenzo[b][1,8]naphthyridine-3-carbonitrile. In the presence of strong electron-donor substituents in the benzene ring the reaction takes another route resulting in 4-amino-2-aryl-6-methoxypyridine-3
在无水甲醇中,在甲醇钠的催化下,丙二腈二聚体的芳基亚甲基衍生物与1,3-环己二酮反应,得到4-氨基-5-芳基-2-甲氧基-6-氧代5,6,7,8,9 ,10-六氢苯并[ b ] [1,8]萘啶-3-甲腈。在苯环中存在强电子给体取代基的情况下,该反应采用另一种途径,从而产生4-氨基-2-芳基-6-甲氧基吡啶-3,5-二腈。

The various inventions and/or their embodiments disclosed herein relate to certain naphthalene diimide (NDI) compounds wherein the NDI groups are bonded to certain subclasses of bridging heteroaryl (hAr) groups, such as the "NDI-hAr-NDI" oligomeric compounds, wherein hAr is a heteroaryl group chosen to provide desirable electronic and steric properties, and the possible identities of the "Rz" terminal peripheral substituent groups are described herein. Transistor and inverter devices can be prepared.

Substituted carbohydrazides 1a - e reacted with ethenetetracarbonitrile (2) in dimethylformamide with formation of diacylhydrazines 4a - e and 5-amino-1-substiuted pyrazole-3,3,4-tricarbonitriles 5a - e. On the other hand, 1a-c reacted with diethyl (E)-2,3-dicyanobutenedioate (3) to give oxadiazinone and pyrazolone derivatives 12a - e and 13a - e, respectively.
