An unexpected opening of a proximal bond in the anellated four-membered ring of benzocyclobutene tricarbonylchromium(0) complexes occurs when the 1-hydroxy-1-hex-5-enyl complex 2 is treated with base: in general, rupture of the distal bond is observed. The reaction of tricarbonyl-η6-(1-oxobenzocyclobutene)chromium(0)1 with primary amines also causes a proximal ring-opening reaction.
当苯并环丁烯三羰基铬(0)络合物的四元环的带环四元环中的近端键意外打开时,用碱处理1-羟基-1-己-5-烯基络合物2:通常,远端键断裂被观察到。三羰基-η的反应6 - (1- oxobenzocyclobutene)铬(0)1与伯胺也引起近侧开环反应。
