Alkyl manganese pentacarbonyl compounds5MnR (R = CH3, p-CH2C6H4CH3, p-CH2C6H4OCH3) were synthesized by metalation of manganese pentacarbony potassium salt with corresponding alkyl halides in ether. Photolysis of these with 1-2 equivalent of (CH3)2(C6H5)SiH or (CH3)(C6H5)2SiH in C6D6 solution at 5℃ produces silyl manganese pentacarbonyl compounds5MnSi(C6H5)(CH3)2 and5MnSi(C6H5)2(CH3) respectively (yield 70-88%).

用五羰基锰钾盐和相应的卤代物在乙醚中的金属化反应合成了五羰基锰烷基合物5MnR（R = CH3，p-CH2C6H4CH3， p-CH2C6H4OCH3 ），产率达到72-93％，将这些化合物与1-2当量(CH3)2(C6H5)SiH和(CH3)(C6H5)2SiH的C6D6溶液在5℃光解，分别得到五羰基锰硅烷基化合物5MnSi(C6H5)(CH3)2和5MnSi(C6H5)2(CH3)（产率达到70-88％）。

In addition, the coordination number of coordination complex formed by phosphorus pentafluoride and aether was calculated and the number decreases from 2.04 to 0.8436 when temperature rises from 0℃ to 30℃; the equation of dissolving rate was also acquired: Y = Bi+2 BiX.

此外还计算了五氟化磷与乙醚形成缔合物的配位数，当T从0℃～30℃时，其值为2.04～0.8436；从试验中得出了不同温度下的溶解速率方程：Y′=B_1+2 B_2X。

The reaction was run in aqueous diethyl ether at 30℃ for 24h under the catalysis of bakers' yeast, which preincubated for 2h in the presence of phenacyl chloride.
