摘要

2 stable when stored in a freezer, but some of them slowly decompose at room temperature. The structures of products 2a-e were determined by their IR and NMFt (lH, 13C) spectroscopy, mass spectrometry, and elemental analy~ is.~ Infrared spectroscopy demonstrates for both keto 2a, b and ester 2c, d, e derivatives significant lowering of the carbonyl frequency, consistent with the presence of an electron-rich center (ylidic carbon) ...
