A bisbiphenylacylphosphine oxide of formula (I) and its preparation method are provided. The formula of —Ar— is
First, 10-chloro-9,10-dihydro-9-oxa-10-phosphaphenanthrene (CDOP) is prepared by using 2-phenylphenol, and then is esterified to synthesize 6-methoxy-(6H)-dibenz[c,e][1,2]oxa-phosphorin (MDOP). Next, acid chloride compounds are added for performing the Arbuzov reaction to synthesize bisbiphenylacylphosphine oxide. CDOP is hydrolyzed to be derived into 9,10-dihydro-9-oxa-10-phosphaphen-anthrene-10-oxide (DOPO), and then DOPO reacts with arylaldehyde to form secondary alcohol. Therefore, bisbiphenylacylphosphine oxide is prepared by using secondary alcohol under oxidation. Also, under a coupling reaction, DOPO reacts with the acid chloride compounds by using a Lewis acid as a catalyst to prepare bisbiphenylacylphosphine oxide.
提供了一种式(I)的双联苯酰膦氧化物及其制备方法。首先,通过使用2-苯基酚制备10-氯-9,10-二氢-9-氧-10-磷杂蒽(CDOP),然后酯化合成6-甲氧基-(6H)-二苯[c,e][1,2]氧-磷杂环戊烷(MDOP)。接下来,加入酸氯化合物进行Arbuzov反应,合成双联苯酰膦氧化物。将CDOP水解得到9,10-二氢-9-氧-10-磷杂蒽-10-氧化物(DOPO),然后DOPO与芳基醛反应形成二级醇。因此,通过在氧化条件下使用二级醇制备双联苯酰膦氧化物。此外,在偶联反应中,DOPO通过使用Lewis酸作为催化剂与酸氯化合物发生反应,制备双联苯酰膦氧化物。
