The method includes dissolving lithium, nickel and cobalt acetate in a solution, adding ammonium dihydrogen phosphate to the solution, adding acid to the solution, heating the solution to a first temperature for a first period of time to form a solid mixer material, and sintering the solid mixer material at a second temperature for a second period of time.
专利号:WO-2023183543-A1 优先权日:2022-03-25 标 题 :Chemoenzymatic synthesis of selenoneine and its analogs 发明人:SEYEDSAYAMDOST MOHAMMAD; KAYROUZ CHASE 权利人:UNIV PRINCETON 摘要:Disclosed is a method for forming selenoneine or analogs thereof. The method may include phosphorylating sodium selenide to a selenophosphate, using adenosine triphosphate (ATP) and at least a first protein, generating a selenosugar by converting the selenophosphate using at least a second protein in the presence of a common sugar donor, and forming selenoneine or an analog thereof by combining the selenosugar with N,N,N-trimethyl-L- histidine or analogs thereof using at least a third protein. The method may include combining SenA, SenB, and SenC in an aqueous buffer at neutral pH and ambient temperature, and allowing SenA, SenB, and SenC to form selenoneine or an analog thereof in the presence of ATP, a common sugar donor, and sodium selenide.

专利号:US-3919325-A 优先权日:1972-03-01 标题 :Process for preparing allylidenphosphoranes 发明人:BOGDANOVIC BORISLAV 权利人:STUDIENGESELLSCHAFT KOHLE MBH 摘要:Allylidene phosphoranes are prepared by a new process comprising reacting dialkyl aluminum alkylidene amides or bis(N-dialkyl aluminum-imino)alkanes which are obtainable from saturated aliphatic nitriles or dinitriles and dialkyl aluminum hydrides with alkylidene phosphoranes R3CH PR34. The allylidene phosphoranes are useful as intermediate products in the synthesis of 1,3-dienes which include insect attracting substances and flavoring agents, and in the synthesis of 1,5-dienes such as squalene.
