Dihydridobis

A highly fluorinated bis(pyrazolyl)borate ligand, dihydridobis(3,5-bis(trifluoromethyl)pyrazo-lyl)borate has been synthesized. The zinc triflate complex was prepared from the potassium salt of the ligand and exhibits distorted tetrahedral coordination which allows comparison of the amount of distortion, in relation to the electronic properties of substituents, with the methylated analog.165...

All reactions are carried out in an inert atmosphere. Solutions of (//6-benzene)dihydridobis(triphenylphosphine)molybdenum should be handled in an inert atmosphere other than nitrogen to avoid contaminating the product with the dinitrogen complex [Mo[P(C6H5)3]2(fj6-C6H6)]2N2. [Pg.57]

Similar TRIR experiments were performed with Tp Rh(CO)2 and Bp Rh(CO)2 [Tp = hydridotris(3,5-dimethylpjn azolyl)borate Bp = dihydridobis(3,5-dimethyIpyrazolyl)borate] in liquid Xe solution at 223 K 48). From the positions of the observed transient infrared bands, it was found that the Tp species forms two xenon complexes upon photolysis, (7j -Tp )Rh(CO)Xe and (>j -Tp )Rh(CO)Xe, and that Bp Rh(CO)Xe is produced from Bp Rh(CO)2.

Caution. As hydrogen is liberated before hydrogenation starts when 2-methoxyethanol reacts with sodium and aluminium, the volume of the reaction mixture must not exceed 55% of the total free volume of the autoclave and the maximum pressure of hydrogen must not exceed the permitted working pressure. This part of the preparation is exothermic and the temperature of the reaction mixture must not exceed 170°. When more than 15 moles of sodium dihydridobis(2-methoxyethoxo)aluminate(l-), is prepared it is necessary to control this reaction by slow addition of 2-methoxyethanol to sodium and aluminum in the closed autoclave.

Sodium dihydridobis(2-methoxyethoxo)aluminate(l-) is a clear or light-yellow viscous liquid (20°) with d o = 1.122 g/cm. Upon cooling to 0-5°, it solidifies... [Pg.151]

Sodium dihydridobis(2-methoxyethoxo)aluminate(l-) is a derivative of NafAlHa] and its behavior is chemically similar to that of the tetrahydrido-aluminates, Na[AlH4] and li[AlH4]. The compound is stable up to 170°, when decomposition begins the decomposition is spontaneous at 214°. ... [Pg.152]
