Title: Process for the racheiization of atropisomeric bis (phospine oxide) compounds
Inventor: KIENZLE FRANK
IPC: C07F9/50
Filed: 2000-07-06
Granted: 2005-09-12
Abstract: The present invention is concerned with a novel process for the racemization of atropisomeric bis(phosphine oxide) compounds of formula I in their (S) or (R) or non-racemic form, for the preparation of optical active bisphosphine ligands, which form optical active complexes with transition metals. These complexes are used as catalysts in a number of asymmetric reactions. The racemization is thermal and carried out in high or low boiling solvent, under normal or elevated pressure at 10<5> to 3.5x10<7> Pa. The heating is performed in a system which allows heating up to 400 DEG C (reactor, autoclave, aluminum block, round-bottom flask with heating/stirring mantle and the like) or by microwave irradiation or in the melt at a temperature from 260 to 400 DEG C, preferably from 280 to 380 DEG C, batchwise or in a continuous manner

Abstract: The channel selecting appts.  tunes two tuning devices to preselected channels for receiving broadcast frequencies.  Seiectively operable channel selecting circuitry is common to the devices for generating and supplying channel selector signals to the devices to determine their tuning condition.  A control device selectively produces a lock-out control signal, and a locking device is coupled to the second tuning device.  The locking device responds to the absence of the cock out control signal and enables the condition of the second tuning device to be determined by the selector signals simul taneously with conditioning the first tuning device.

Abstract: The stacked memory cell is  mfd.  by  (a)  defining  a  field region, and  then  depositing  a  first  oxide  film  (2)  on  the semiconductor substrate (13) to lift off an insulating film (2) of the channel region, (b) forming a gate  oxide  film  (1a)  on  the exposed substrate (13) and a low density impurity  region  on  the layer (2)-formed substrate (3), (c) depositing a polysilicon and a second oxide film on the whole surface to form a wordline (3)  and a cap gate oxide film (4), (d) forming a side wall spacer  (5)  on the side wall of the wordline, and then  forming  a  high  density impurity region and a source/drain region (12), and (e) forming  a storage node contact hole, a bitline  contact  hole,  a  capacitor storage node (7b), a bitline contact plug (7a), a dielectric  film (8), a plate (9) and a bitline (11).
