Стереоселективное нуклеофильное присоединение кетонов к арилацетиленам
Диссертация
Однако, такая логика, ставящая под сомнение вероятность основно-каталитического винилирования кетонов ацетиленами, не учитывает возможности электрофильного содействия со стороны катиона щелочного металла, который может стабилизировать образующийся карбанион. Кроме того, образующиеся третичные ацетиленовые спирты при нагревании обычно диссоциируют по обратной реакции Фаворского на исходные… Читать ещё >
