摘要:The invention pertains to a method for the synthesis of specific alkenyl-phosphorous compounds according to formula (I)whereinR¹and R²are independently selected from hydrogen or a substituted or unsubstituted C_1-40hydrocarbon group, whereby the group optionally contains at least one heteroatom, preferably O, N or S;X is independently O or S;R³and R⁴are independently selected from a substituted or unsubstituted C_1-40hydrocarbon group, whereby the group optionally contains at least one heteroatom, preferably O, N or S;m is independently 0 or 1; andn is an integer from 1 to 4. Furthermore, the invention relates to compounds obtained by this method, and compositions comprising the compounds of the present invention, wherein the compositions are compositions for lighting applications, optical applications, microelectronic compounds, optical brighteners or are detergent compositions. Finally, the invention relates to the use of the compounds of the present invention in lighting lighting applications, optical applications microelectronic compounds, optical brighteners or detergent compositions.

摘要:The invention relates to processes for the synthesis of tertiary phosphine oxides and sulfides. The process according to the invention consists, in a first step, of reacting a secondary phosphine oxide or sulfide with an optionally activated alkali metal amide, and, in a second step, of reacting the mixture obtained in the first step with an organic halide containing at least one halogenophenyl radical or one halogenomethyl group. Tertiary phosphine oxides and sulfides are complexing agents of high stability.

标题:Method for synthesizing C-glycosides of ulosonic acids
发明人：LINHARDT ROBERT J; VLAHOV IONTCHO R
权利人:UNIV IOWA RES FOUND
摘要:A method for synthesizing C-glycosides of ulosonic acids such as Neu5Ac, by which diastereocontrolled synthesis of α-C-glycosides of ulosonic acids is attained is disclosed. In the method of the present invention, an ulosonic acid sulfone or phosphite is reacted with an aldehyde or ketone compound in the presence of a lanthanide metal halide.
