Synthesen und Eigenschaften ethinylierter und trimethylsilylethinylierter Molek�lsysteme mit 1,6-Methano[10]annulen-Partialstruktur
摘要:
2-Trimethylsilylethinylated 1,6-methano[10]annulene 1 a was obtained by reaction of 2-bromo-1,6-methano[10]annulene with trimethylsilylacetylene in the presence of bis-(triphenylphosphin-)-Pd (II) chloride and Cu(I) and also by reaction of 1,1-diiodo-2-(1,6-methano[10]annulene-2-yl)-ethene (2) with n-buthyl-lithium followed by hydrolysis. 1 a reacts with 2N NaOH to 2-ethinyl-1,6-methano[10]annulene (1 b). 2,7- and 2, 10-dibromo-1,6-methano[10]annulene can be substituted to give the trimethylsilylethinylated compounds 3 a-6 a, which then can be transformed with 2N NaOH into the desilylated products 3 b-5 b.

The stepwise palladium-catalyzed coupling of dibromo-1,6-methano[10]annulene derivatives to a phenyl-acetylene substituted by an electron-withdrawing group followed by coupling with a phenylacetylene possessing an electron-donating group allows the preparation of donor/acceptor systems which contain three aromatic moieties linked by ethynediyl bridges. The same type of cross-coupling starting from 2-ethynyl-1
