Synthetic studies of substituted 2,3-naphthalocyanines
摘要:
A series of di- and tetra-substituted 2,3-dicyanonaphthalenes were prepared which were converted into the respective 2,3-naphthalocyaninato zinc complexes. The synthetic pathways to and the spectroscopic properties of these novel compounds are described. (C) 1997 Elsevier Science Ltd.

Cycloadditionreactions of 1,4-dihydro-1,4-epoxynaphthalenes (2) and benzo[c]furans (4), generated in situ from the tetracyclone adducts of 2, yield the diepoxynaphthacenes 5 (Schemes 1, 2). Out of 4 possible stereoisomers an exo-exo and an exo-endo geometry (A and C in Scheme 3) can be realized. The ratio A:C varies from pure A to pure C depending on the substituents of 2 and 4. Stereoisomeric heptacenes
1,4-二氢-1,4-环氧萘(2)和苯并[ c ]呋喃(4)的环加成反应是由四环酮加合物2原位生成的,生成双环氧萘5(方案1、2)。在4种可能的立体异构体中,可以实现exo-exo和exo-endo几何形状(方案3中的A和C)。比值A:C从纯A到纯C取决于取代基而变化2和4。立体异构庚烯7可以通过相同类型的两倍环加成获得(方案4)。反应性炔烃(例如环辛炔或炔二羧酸酯)只有一个π键能够加成4(方案5、6)。

DOI:10.1021/ol8003468
日期:2008.8.7
Expedient, facile syntheses of highly fluorinated benzobisbenzothiophenes (BBBT) are reported. Defined peripheral arrangements of sulfur and fluorine atoms lead to extensive crystalline networks of edge-to-edge S-F close contacts. The effects of various substitution patterns on self-assembly and electronic properties are described.
