标 题:Synthesis of cis-olefins
发明人：BYERS JIM D
权利人:PHILLIPS PETROLEUM CO
摘要:A process for the synthesis of cis-olefins from cis-olefinic alcohols consisting essentially of the following steps: n (a) reacting a cis-olefinic alcohol with a source of an alkali metal ion selected from the group consisting of lithium and sodium ions to form a first reaction product, n (b) then contacting said thus formed first reaction product with a sulfonyl halide compound to form a second reaction product, n (c) then containing said thus formed second reaction product with an alkyl magnesium compound and a cuprous salt to form a third reaction product comprising a cis-olefin wherein said steps are carried out in a suitable organic solvent.

标题 :Synthesis of boronic esters and boronic acids using grignard reagents
发明人：CLARY JACOB W; SINGARAM BAKTHAN
权利人:CLARY JACOB W; SINGARAM BAKTHAN; UNIV CALIFORNIA
摘要:Boronic esters and boronic acids are synthesized at ambient temperature in an ethereal solvent by the reaction of Grignard reagents with a boron-containing substrate. The boron-containing substrate may be a boronic ester such as pinacolborane, neopentylglycolborane, or a dialkylaminoborane compound such as diisopropylaminoborane. The Grignard reagents may be pre-formed or generated from an alkyl, alkenyl, aryl, arylalkyl, heteroaryl, vinyl, or allyl halide compound and Mg 0 . When the boron-containing substrate is a boronic ester, the reactions generally proceed at room temperature without added base in about 1 to 3 hours to form a boronic ester compound. When the boron-containing substrate is a dialkylaminoborane compound, the reactions generally proceed to completion at 0° C. in about 1 hour to form a boronic acid compound.
