摘要

SiMe3) in toluene also forms [6+ 21 cycloadducts [(V~:~-C~ H~ N {CO~ E~} R'~) C~(CO)~](6). The heterobicyclotrienes 7 are isolated from 6 by treatment with iodine (R'= SiMe3) or by heating in toluene (R'= Ph). X-ray crystal structures are reported for 6b (R'= SiMe3)[orthorhombic, P212121, a= 8.871 (1), b= 10.148 (1), and c= 26.017 (4) A, R= 0.041 for 2500 independent reflections] and a byproduct (8) that results from the endo [6+ 41 ...
