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.

thereby generating two highlyreactive 8π systems (Scheme 1). In the presence of 1,4-dihydro-1,4-epoxynaphthalenes 2, the dithiaheptacene derivatives 3 are formed, dehydration of which leads to the compounds 4 and 5 (Scheme 2). Repetitive cycloaddition reactions of 1 with the twofold 2π component 11 (Scheme 3) yield the oligomers 15 with statistically bent (and possibly cyclic) structures (Schemes 4 and 5)
苯并[1,2- b:4,5- b ']双硫杂环丁烷(1)经历4元环的逐步热打开,从而生成两个高反应性的8π系统(方案1)。在1,4-二氢-1,4-环氧萘2的存在下,形成了二噻庚烯衍生物3,其脱水生成化合物4和5(方案2)。具有双重2π组分11的重复的1的环加成反应(方案3)产生具有统计上弯曲的(并且可能是环状的)结构的低聚物15(方案4和5)。而15和相关的低聚物14由于可自由溶于许多有机溶剂,因此脱水系统16(方案6)完全不溶。

The angular benzobisthietes 3 and 5 could be prepared by synthetic sequences in which the final step was in both cases a twofold dehydration of the corresponding bis(hydroxymethyl)dimercaptobenzenes 10 and 14, respectively. Flash vacuum pyrolysis conditions were used for the generation and isolation of 3 and 5 which are highly reactive bisdiene systems. Cycloaddition reactions with the dienophiles 15 and 18a,b led to the adducts 16, 17, and 19a,b. (C) 1998 Elsevier Science Ltd. All rights reserved.
