Abstract

Die losen Enden verknupft: N-Ts-verbruckte Bisallene (N-Ts=N-(p-Tolylsulfonamid) liefern in Gegenwart eines kationischen Gold-NHC-Katalysators (NHC=N-heterocyclisches Carben) neuartige Cycloisomerisierungsprodukte, 6,7-Dimethylenazabicyclo[3.1.1]heptane, in hohen Ausbeuten (siehe Schema; IPr=N,N′-Bis(2,6-diisopropylphenyl)imidazol-2-yliden).

Abstract

Cycloisomerization of 1,6-enynes to 1,4-dienes proceeded smoothly in the presence of a gold(I) catalyst under mild reaction conditions, and cyclized 1,4-dienes were isolated in good yields. The catalytic system can tolerate the oxygen and nitrogen tether in the substrate.

Abstract

were developed for thecarbonate ion selective electrodes. Calix[4]arene lower rimwas utilized for the successful ion binding site frequentlydue to the proper size as well as rigidity. We introduced twotrifluoroacetyl benzyl moieties at the lower rim of calix-[4]arenes and investigated their binding properties. Two anion receptors 2a and 2b containing p-trifluoro-acetylbenzyl group at the lower rim of calix[4]arene areobtained in high yield by the reaction of calix[4]arene and p-trifluoroacetylbenzyl bromide in the presence of K
