We transformed RMgBr into R-Ti derivatives with the production of byproduct MgBrO~(i-Pr at the same time, but we didn\'t need romove the Mg salt by centrifugation or chelating reagents, for bis[2-(N,N-dimethylamino)ethyl] ether could chelate with Mg atom and thereby reduced the Louis acidity of Mg salt, so we used R-Ti derivatives produced in situ to alkylate the aldehydes induced by BINOL-Ti complexes..
我们通过利用TiO~(i-Pr_4使格氏试剂转化成烷基钛,同时产生具有亲核加成促进作用的副产物MgBrO~(i-Pr,由于BDMAEE能与MgBrO~(i--Pr络合降低其路易酸活性,所以不需要离心或者借助络合试剂完全除去镁盐,而使用原位生成的烷基钛在BINOL-Ti诱导下对醛进行不对称加成。

This blowing fan has a hub connected to the rotating shaft of a motor and a number of blades mounted on the outside surface of the hub at fixed intervals to flow air in the centrifugal direction of the fan. Although this fan is produced in a shape of axial fan or diagonal fan by integrally forming the separate turbo blade on the tip or trailing edge of the rotor blade, the blowing noise can be reduced in addition to the increase in the entire wind quantity of the fan by embodying the optimum set angle of the turbo blade.
由连接在电动机的旋转轴上的轮毂和按一定间隔安装在上述轮毂外周面上的多片叶片构成、使空气向风扇的离心方向流动的送风风扇,虽然制作成将另外的涡轮叶片形成在旋转叶片的叶梢或后沿上而与其成为一体的轴流式风扇和斜流式风扇的形式,但通过实现上述涡轮叶片的最合适的设置角度,便使整个风扇的风量增大,同时减小送风噪音。
