Orthogonal connection of acenes via two-fold Diels-Alder reactions
摘要:
Novel bis-acenes are described whose acene subunits are held in an almost orthogonal geometry by silicon-spiro centers. The synthesis involves Diels-Alder active bis-dienes with orthogonal five-membered rings.
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.
