标题:Synthesis of methyl malvalate and methyl 5,6-methano-5-undecenoate
发明人：GENSLER WALTER J

摘要:This invention relates to the preparation of methyl malvalate, methyl 5,6-methano-5-undecenoate and the preparation of some new intermediates. Malvalic acid, the major cyclopropene component in cottonseed oil, has been synthesized. When 1-chloro-7-hexadecyne reacts with diazoacetic ester in the presence of copper bronze, the ester of 1-chloro-7,8-carboxymethano-7-hexadecene is formed. Treating the corresponding acid chloride with zinc chloride causes loss of carbon monoxide. Either sodium borohydride or lithium aluminum hydride reduces the resulting cyclopropenium compound to 1-chloro-7,8-methano-7-hexadecene. Replacing the chloro group with cyano yields malvalonitrile, which can be converted to methyl malvalate. An analogous sequence of steps has been applied to 1-chloro-4-decyne to produce methyl 5,6-methano5-undecenoate. An alternate synthesis of methyl malvalate starts by using 1-chloro-7-hexadecyne as the precursor for methyl 8heptadecynoate. This acetylenic ester is converted to 8,9carboxymethano-8-heptadecenoic acid, the diacid chloride of which decarbonylates selectively in the presence of metallic chlorides to form the cyclopropenium-acid chloride. After esterification the resulting cyclopropenium-ester is reduced with borohydride to methyl malvalate.

摘要:Provided are methods to convert—through a bottom-up approach—binary and ternary titanium carbides, nitrides, borides, phosphides, aluminides, and silicides into lepidocrocitic nanofilaments that in some cases self-assemble into 2D flakes by immersing them in a quaternary ammonium solution at moderate temperatures. The resulting flakes can comprise nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances.

摘要:Provided are methods to convert - through a bottom-up approach – binary and ternary titanium carbides, nitrides, borides, phosphides, aluminides, and silicides into nanofilaments that in some cases self-assemble into 2D flakes by immersing them in a quaternary ammonium solution at moderate temperatures. The resulting flakes can be C-containing anatase-based layers that are in turn comprised of nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances. Electrodes made from these materials performed well in energy systems. The materials also reduce the viability of some cancer cells. Also provided are mesoporous materials, devices, and related methods.

摘要:There is provided a method for synthesizing a new synthetic composition of ultra-large pore crystalline material which can be used as a sorbent or catalyst component for conversion of organic and inorganic compounds. The crystalline material product of this method exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25° C. This material may have a hexagonal electron diffraction pattern that can be indexed with a d 100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units. The reaction mixture for preparing this material is prepared by forming a solution containing a source of an oxide, followed by adding a gelling reagent to this solution to form a gel.

摘要:The present invention relates to a novel process for the manufacture of metal borides by reaction of a metal source and hydride-containing boron source in a molten salt solvent. The present invention also relates to metal boride materials obtainable by this process. The process allows obtaining the desired metal boride without the need for extremely high temperatures, and is capable of providing the metal borides in crystalline form without the need for a subsequent annealing step. The metal boride obtained by the process may be porous, may have a certain morphology, or may be in the form of metal boride particles that are encapsulated in a shell of boron nitride or amorphous boron. n Additionally, the present invention relates to the use of compounds having polarizable anions for adjusting and controlling the particle size and/or morphology of a product produced in a molten salt reaction mixture.
