A mild,efficient and selective iodination of aromatic compounds using iodine and 1,4-bis(triphenylphosphonium)-2-butene peroxodisulfate

A simple and efficient method for the iodination of aromatic compounds has been achieved in the presence of iodine and 1,4- bis（triphenylphosphonium）-2-butene peroxodisulfate.

A novel and efficient synthesis of alkyl thiocyanates from alkyl halides in water using phase transfer catalysts

1,4 二度(triphenylphosphonium )-2-butene 二氯化物(BTPBDC ) 和 1,4 二度(triphenyl 磷根)-2-butene dithiocyanate (BTPBDT ) 被准备并且用作阶段转移催化剂。烷基卤化物在水里在温和反应条件下面高效地被变换成相应烷基 thiocyanates。为反应的副产品被观察的 isothiocyanates 的形成的没有证据。
