Abstract: Optically active compounds having a chlorine atom attached to the chiral carbon atom such as 2-bromoaliphatic acids can be racemized without by-product formation by heating an acidified solution of the organic acid at a temperature sufficient to accomplish racemization, the solution being substantially devoid of ionized halogen other than bromine ions. The preferred acidifying agent is hydrobromic acid. The use of hydrochloric acid causes extensive by-product formation.

Abstract: A method of chemical vapour deposition characterised in that it comprises:

(A) producing a first gas stream comprising a Group III organometallic gas and a carrier gas;
(B) producing a second gas stream comprising an elemental Group V metal gas from an elemental source and a carrier gas; and
(C) supplying said gas streams to a reactor where they react to form a III-V semiconductor; and, optionally
(D) supplying hydrogen gas to said reactor is disclosed.

A chemical vapour deposition apparatus characterised in that it comprises:

(A) first means (8) for producing a first gas stream comprising a Group III organometallic gas and a carrier gas;
(B) second means (6) for producing a second gas stream comprising an elemental Group V metal gas from an elemental source and a carrier gas; and
(C) a reactor (4) to which said gas streams are supplied where they react to form a III-V semiconductor; and, optionally,
(D) third means for supplying hydrogen gas to said reactor is also disclosed.

The present invention provides advantages over the prior art.
The arsine, phosphine and trimethyl triethyl, or trialkyl arsine or trialkyl phosphine adducts of triethyl or trimethyl indium sources of the prior art are replaced by one or more pnictide (Group V) bubblers; that is, heated sources of elemental pnic- tides through which a carrier gas is allowed to flow. The elemental pnictide gas and the carrier gas are supplied in a stream as are a Group III organometallic gas, a carrier gas, and hydrogen to a chemical vapour deposition reactor where they react to form III-V semiconductors surface layers on a substrate. The carrier gas may be nitrogen, or a noble gas, such as argon. Alternatively, hydrogen may be used as the carrier gas so that the reaction is carried out in an exclusive hydrogen atmosphere. At least some of this hydrogen may be monoatomic hydrogen. The substrate may be a III-C semiconductor or glass. Products include layers of gallium arsenide, indium phosphide and alloys thereof, including gallium indium arsenide and gallium aluminium arsenide. Other ternary and quaternary III-V semiconductors are produced using appropriate combinations of sources of Group III organometallic gases and Group V elemental gases produced by bubblers. The products may be used in semiconductor devices including solar cells.

Abstract: A process is disclosed for preparing alkyldiarylphosphines and related compounds. In such process a compound having the structural formula:
wherein :

Z is an atom from group VA of the periodic table;
Y is any radical that is essentially incapable of reacting with an alkali metal;
X is any radical that is essentially incapable of reacting with an alkali metal;
W is a substituted or unsubstituted aryl, alkyl, arylalkyl, or alkylaryl radical or hydrogen; and
is prepared by reacting a first halide with a molten alkali metal or amalgam thereof in the presence of an inert solvent to form a first reacted mixture which is reacted with a second halide wherein an amount of the alkali metal or amalgam thereof is used in an excess of less than 100% and the yield of the product is greater than 70%. Typically, diphenylphosphinous chloride is reacted in solution with an excess of an alkali metal; and the reaction product reacted with chorohex- ane thereby forming hexyldiphenylphosphine. The improved process produces greater yields, by use of critical amounts of alkali metal; use of a single reactor rather than two reactors; preinitiation of the first stage reaction reduction of temperatures to increase reaction rate under certain conditions; and preferred reactants and physical form thereof. Novel products include behenyldiphenylphosphine.

Abstract: 57 Improved methods for preparing metal alkoxides from metals and alcohols involve dry-grinding the metal in an inert atmosphere prior to the addition of the alcohol. When an activator is used, it is usually ballmilled with the metal. Higher yields are obtained particularly when the metal and alcohol are not very reactive without an activator. Typical metals are those from Groups 2A, 2B, 3A, and 3B, particularly aluminum, magnesium, and yttrium. Typical alcohols are those which contain up to 16 carbon atoms, particularly those containing 4 or more carbon atoms.
