摘要:The invention relates to the synthesis of tertiary phosphine oxides and also to certain tertiary phosphine oxides. According to the invention, an organic phase containing a halogenomethyl derivative, a secondary phosphine oxide and a phase transfer catalyst in an organic medium is reacted with an aqueous phase containing an inorganic base. The halogenomethyl derivative can be a micromolecule or a macromolecule. The tertiary phosphine oxides are substances which are useful, in particular, in fireproofing, in hydrometallurgy and in the field of plant health.

标 题:Direct synthesis of organotin alkoxides
发明人：JILEK ROBERT E; REED CHRISTOPHER J; NOVAS BRYAN
权利人:INPRIA CORP
摘要:Synthesis techniques are described for forming organotin trialkoxide compounds via direct alkylation of tin alkoxides. A first method involves reacting an alkali metal tin trialkoxide with an organohalide compound (RXn, where X is a halide atom and n≥1) to form a monoorgano tin trialkoxide represented by the formula R[Sn(OR′)3]n. The method can be used to form polytin trialkoxide compounds with a plurality of radiation sensitive C—Sn bonds. R and R′ include organo groups and can optionally comprise hetero-atoms and/or unsaturated bonds. A second method involves the ultraviolet light-driven reaction of a di-tin tetraalkoxide with an organohalide compound (RX) to form a monoorgano trialkoxide represented by the formula RSn(OR′)3. A third method involves the visible or ultraviolet light-driven reaction of a di-tin tetraalkoxide or an alkali metal tin trialkoxide with an fluorinated organohalide compound (RFX) to form a fluorinated monoorgano trialkoxide represented by the formula RFSn(OR′)3. The disclosed methods provide for high mono-organo specificity. Corresponding organotin trialkoxide compositions are also described. The compositions are useful for radiation patterning, especially with EUV radiation. The organotin trialkoxide compositions may be formed as radiation-patternable coatings on substrates.

标题:Synthesis of macrocyclic tetraamido-N ligands
发明人：GORDON-WYLIE SCOTT W; COLLINS TERRENCE J
权利人:UNIV CARNEGIE MELLON
摘要:New synthetic methods for the preparation of macrocyclic amido-N donor ligands are provided. The primary method of the present invention involves in general only two synthetic steps. In the first step, an α or β amino carboxylic acid is allowed to react with an optimal (approximately stoichiometric) amount of an activated malonate or oxalate derivative with mild heating. Upon completion of the double coupling reaction, hydrolysis of the reaction mixture yields a diamide containing intermediate (a macro linker). In the second step, stoichiometric amounts of a diamine, preferably an orthophenylene diamine, are added to the macro linker intermediate in the presence of a coupling agent and heat. This second double coupling reaction, is allowed to proceed for a period of time sufficient to produce a macrocyclic tetraamido compound. The substituent groups on the α or β amino carboxylic acid, the malonate, and the aryl diamine may all be selectively varied so that the resulting tetraamido macrocycle can be tailored to specific desired end uses. The macrocyclic tetraamide ligand may then be complexed with a metal, such as a transition metal, and preferably the middle and later transition metals, to form a robust chelate complex suitable for catalyzing oxidation reactions.
