    Abstract: A method of growing group III-nitride crystals in a mixture of supercritical ammonia and nitrogen, and the group-III crystals grown by this method. The group III-nitride crystal is grown in a reaction vessel in supercritical ammonia using a source material or nutrient that is polycrystalline group III-nitride, amorphous group III-nitride, group-III metal or a mixture of the above, and a seed crystal that is a group-III nitride single crystal. In order to grow high-quality group III-nitride crystals, the crystallization temperature is set at 550 °C or higher. Theoretical calculations show that dissociation of NH 3 at this temperature is significant. However, the dissociation of NH 3 is avoided by adding extra N 2 pressure after filling the reaction vessel with NH 3 .

    Abstract: The present invention is directed to a process of making α-aminooxyketone and α-­hydroxyketone compounds. The synthetic pathway generally involves reacting an aldehyde or ketone substrate and a nitroso substrate in the presence of a catalyst of formula (IV), wherein X 1 -X 3 represent independently nitrogen, carbon, oxygen or sulfur and Z represents a 4 to 10-membered ring with or without a substituent and optionally a further step to convert the α-aminooxyketone compound formed to the α-hydroxyketone compound. The present invention results in α-aminooxyketone and α-hydroxyketone compounds with high enantioselectivity and high purity. The present invention is also directed to a catalytic asymmetric O-nitroso Aldol / Michael reaction. The substrates of this reaction are generally cyclic α,ß-unsaturated ketone substrate and a nitroso substrate. This methodology generally involves reacting the cyclic α,ß-unsaturated ketone substrate and the nitroso substrate in the presence of a proline-based catalyst, to provide a heterocyclic product.
