Method of preparing and obtaining symmetric and asymmetric substances by funcionalizau00e7u00e3o differential of salts of symmetrical fosfu00c8nio

摘要

Method of preparing and obtaining symmetric and asymmetric funcionalizau00e7u00e3o substances by differential salt fosfu00c8nio symmetrical.The present invention relates to a method of preparing and obtaining of aliphatic or aromatic substances, symmetric and asymmetric, funcionalizau00e7u00e3o salts of di - phosphonium symmetrical.With the application to the control of pests of coffee.The method enables the attainment of sexual feromu00f3nios synthesized three insects - Prague: leucoptera coffeelia, lambdina athasaria and lambdina pellucidatia.
