标题:硫代磷酸盐--一种多功能的益生元试剂
摘要:描述的是我们对硫代磷酸盐在与我们之前报道的氰硫系统化学相关的环境中的反应性的初步研究.硫代磷酸盐以高效的方式添加到各种腈基中,产生相应的硫代酰胺,并简要讨论了其机理含义.硫代磷酸盐也可以作为磷酸化剂,腺苷证明了这一点.硫代磷酸盐的益生元可用性必须受到质疑,但如果能够找到合理的合成方法,那么它为益生元化学领域带来的优势似乎是非常有益的.

标题 :Synthesis of terminal alkenes from internal alkenes via olefin metathesis
发明人：SCHRODI YANN; PEDERSON RICHARD L; KAIDO HIROKI; TUPY MICHAEL J
权利人:ELEVANCE RENEWABLE SCIENCES
摘要:This disclosure relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by an olefin metathesis catalyst. According to one aspect, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting, in the presence of a ruthenium alkylidene metathesis catalyst, an olefinic substrate comprised of at least one internal olefin with a cross metathesis partner comprised of an alpha olefinic reactant, under reaction conditions effective to allow cross-metathesis to occur, wherein the reaction conditions include a reaction temperature of at least 35° C. The methods, compositions, reactions and reaction systems herein disclosed have utility in the fields of catalysis, organic synthesis, and industrial chemistry.
