摘要

Abstract: Irradiation of 3, 6-dimethoxy-9-diazofluorene gives 3, 6-dimethoxy-9- fluorenylidene. This carbene was detected in frozen media by low-temperature optical spectroscopy and at room temperature in fluid solution by nanosecond laser techniques. The EPR spectrum of the diazo compound irradiated at low temperature does not show any characteristic triplet carbene signals. The carbene reacts with methyl alcohol at ...
