Six new dicationic 2D nonlinear optical (NLO) chromophores with pyrazinyl-pyridinium electron acceptors have been synthesized by nucleophilic substitutions of 2,6-dichloropyrazine with pyridyl derivatives. These compounds have been characterized as their PF(6)(-) salts by using various techniques including electronic absorption spectroscopy

Cyclooligomerization of 2,6-dichloropyrazine 4 and benzyl 2,3-dihydroxybenzoate 5 under microwave irradiation resulted in a racemic pair of ester functionalized ortho-linked oxacalix[2]benzene[2]pyrazine 6, which was further transformed to the corresponding racemic carboxylic acid functionalized ortho-linked oxacalix[2]benzene[2]pyrazine 3. Both enantiomers of 3
Synthesis of oxacalixarenes incorporating nitrogen heterocycles: evidence for thermodynamic control.

[structure: see text] Oxacalix[2]arene[2]hetarenes are formed in a single step by cyclooligomerization of meta-diphenols with meta-dichlorinated azaheterocycles. The high selectivity for cyclic tetramer formation results from thermodynamic product control. Macrocycles as large as oxacalix[5]arene[5]hetarenes have been isolated under nonequilibrating conditions.
