摘要

Rules are often honored by exceptions. Consider the proposition:" if a singlet carbene has an internal insertion or cy-cloaddition available, it will not be possible to trap it efficiently with an external reagent".'Cyclopropylcarbene, for example, readily ring expands to cyclobutene* or fragments to ethylene and a~ etylene;*~-~,~ external traps, alkenes in particular, should be hard pressed to compete with these facile intramolecular modes of escape. One way to ...
