NaHCO 3 is an ingredient of some over-the-counter medications that react with excess stomach acid, but NaOH is far too strong a base, and therefore far too dangerous, for that. This is another reaction-solubility test; bicarbonate ion reacts with carboxylic acids but not with phenols to ...
14.2.3 与有机金属化合物的反应 (Reaction of carboxylic acid derivatives with organometal compound) 1、羧酸衍生物与格氏试剂的反应 羧酸衍生物均可于格氏试剂反应得到酮,过量格氏试剂得叔醇,有空间位阻的反应物可满意地得到酮。 酸酐与酰胺由于消耗较多的格氏试剂而很少用于合成。如: 12 有机化学电子教案 第十...

In the literature, certain halovinylcarboxylic acid derivatives are proposed as active ingredients of pesticides. The biological properties of those known compounds are not entirely satisfactory in the field of pest control, however, and there is therefore a need to provide further compounds having pes...
