Açıklama
Five 6-halogeno-binaphthyl derivatives of different structure were synthesised starting from 2,2'-dihydroxy-1,1'-binaphthyl 1. Several new 6-substituted binaphthyl compounds were obtained via the palladium-catalysed reactions of these derivatives. The reactivity of 6-iodo derivatives was much greater in most cases. In cross-coupling reactions the 6-bromo compounds were converted into the products using longer reaction times and/or higher temperatures. The reactivity difference between the two types of substrates was especially marked in aminocarbonylation and Heck reactions. (C) 2011 Elsevier Ltd. All rights reserved.
