The bridging methylidyne clusters [Co3(CO)9η1-μ3-[CP(O)(OR)2])] 1 (R = Et) and 3 (R = SiMe3) with α-phosphoryl substituents have been synthesized by reaction of Cl3C-P(O)(OR)2 with Co2(CO)8, followed by protonation. Cluster 3 was also obtained by the reaction of 1 with Me3SiBr. The structure of 1 has been determined by X-ray crystallography. The donor properties of the P=O function toward Lewis acids
桥接次甲基簇[CO 3(CO)9 η 1 - μ 3 - [CP(O)(OR)2 ])] 1(R = ET)和3(R =森达3)与α -磷酰基的取代基具有通过使Cl 3 C-P(O)(OR)2与Co 2(CO)8反应,然后进行质子合成,合成了α-己内酰胺。簇3也通过1与Me 3 SiBr的反应获得。1的结构已经通过X射线晶体学确定。对路易斯酸,例如[Cp 2 MCl] +(M = Ti,Zr)的P = O功能的给体性质用于组装早期的晚期金属体系。
