Patent number: 4812586Abstract: A method of preparing high purity dimethyl cadmium or dimethyl zinc suitable for use in the deposition of Group II-VI epitaxial layers, which consists of forming an adduct of the metal alkyl with a non-chelating tertiary amine containing at least two tertiary amino groups per amine molecule, and subsequently dissociating the adduct to liberate the metal alkyl as a vapor. The adducts formed during the preparative method are found to dissociate readily on heating and yet are substantially involatile and so do not contaminate the liberated metal alkyl. A preferred amine suitable for use in the preparative method is 4,4' bipyridyl.Type: GrantFiled: January 27, 1987Date of Patent: March 14, 1989Assignee: The Secretary of State for Defence in Her Britannic Majesty's Government of the United Kingdom of Great Britain and Northern IrelandInventors: John B. Mullin, John C. Hamilton, Elisabeth D. Orrell, Philip R. Jacobs, Deodattta V. Shenai-Khatkhate

Patent number: 4800224Abstract: Optically active compounds of the formula I ##STR1## in which R.sup.1 is C.sub.1 -C.sub.4 -alkyl, phenyl or benzyl, R.sup.2 is a radical of the formula II or IIa ##STR2## in which R.sup.3 is H or --CH.sub.3, or R.sup.1 and R.sup.2 together form a radical of the formula ##STR3## in which R.sup.2 has the meaning given above; and * represents predominantly R or predominantly S configuration.The compounds can be polymerized to give homopolymers or copolymers. The compounds and the polymers can be complexed with iridium(I) salts in the presence of a diene. The complexes are suitable as enantioselective catalysts.Type: GrantFiled: May 8, 1987Date of Patent: January 24, 1989Assignee: Ciba-Geigy CorporationInventor: Jurgen Kaschig

Patent number: 4659829Abstract: The invention concerns peroxide complexes of metals complying with the general formula LnMXpY, wherein M is a metal selected from groups VIII, IB and VIIB, particularly cobalt, X is an anionic group, for example carboxylate, R is an alkyl, cycloalkyl or arylalkyl group, n=1 or 2, p=0 or 1 and n+p=2.L is a tridentated ligand from the group of 1,3 bis (2-pyridylimino) isoindolines.These complexes are obtained by reaction of a hydroperoxide ROOH with a complex of formula LnMXp. They can be used in oxidizing hydrocarbons to a mixture of alcohols and ketones, either as reactants or as catalysts.They are particularly useful to prepare tert-butanol by oxidation of isobutane in liquid phase, by means of an oxygen-containing gas such as air.Type: GrantFiled: January 31, 1985Date of Patent: April 21, 1987Assignee: Institut Francais du PetroleInventors: Lucien Saussine, Alain Robine, Hubert Mimoun

Patent number: 4394156Abstract: The present invention relates to novel active compounds having a plant growth-inhibiting and herbicidal action and their preparation and to agents containing these active ingredients, and their use.The novel active compounds are saturated and unsaturated 4-membered to 7-membered ring nitrogen heterocyclic compounds which are substituted on the nitrogen atom by a phenyl radical which itself carries a trifluoromethanesulphonamido group -NH-SO.sub.2 -CF.sub.3 as a substituent. The phenyl radical can also carry other substituents and the heterocyclic structure can also be substituted. Oxo derivatives of the heterocyclic compound, in which the oxo group is preferably adjacent to the nitrogen atom, form a preferred sub-group of compounds.Type: GrantFiled: October 26, 1981Date of Patent: July 19, 1983Assignee: Ciba-Geigy CorporationInventors: Hans Tobler, Werner Fory, Rolf Schurter
