Web11 de abr. de 2024 · These factors include a catalyst, any chemical substance that either increases or decreases the rate of a chemical reaction. Catalysts are neither consumed in the reaction nor do they alter the end products of the reaction. Secondly, in many chemical reactions, the rate of the chemical reaction is directly proportional to the temperature. WebDespite recent advancements in the development of catalytic asymmetric electrophile induced lactonization reactions of olefinic carboxylic acids, the archetypical …
