摘要:The invention is directed to the cross-metathesis and ring-closing metathesis reactions between geminal disubstituted olefins and terminal olefins, wherein the reaction employs a Ruthenium or Osmium metal carbene complex. Specifically, the invention relates to the synthesis of α-functionalized or unfunctionalized olefins via intermolecular cross-metathesis and intramolecular ring-closing metathesis using a ruthenium alkylidene complex. The catalysts preferably used in the invention are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are each independently an anionic ligand; n L is a neutral electron donor ligand; and, n R, R 1 R 6 , R 7 , R 8 , and R 9 are each independently hydrogen or a substituent selected from the group consisting of C 1 -C 20 alkyl, C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl.

摘要:An improved regiospecific synthesis of organic phosphonous acids, comprising of hydrophosphorylation of an olefin with hydrophosphorous acid in the presence of an inorganic persulfate, which acts as a source of free radicals at a pH ranging from 4.5 to 7.0, in which the orientation of addition is anti-Markonikoff. The process enables production of organic phosphonous acids at lower temperature and atmospheric pressure under milder pH conditions for better regioselectivity in hydrophosphorylation and obtain the phosphonous acid with good yield and purity following simple isolation procedure. Phosphonous acids obtained by the process are commercially valuable as effective detergents and wetting agents, lubricants and lubricant additives, plasticizers for plastics and resins, corrosion inhibitors, chemicals including insecticides and pesticides, cobalt extractants and as key intermediates for preparation of commercially important angiotensin converting enzyme (ACE) inhibitors.

摘要:The invention pertains to the use of Group 8 transition metal carbene complexes as catalysts for olefin cross-metathesis reactions. In particular, ruthenium and osmium alkylidene complexes substituted with an N-heterocyclic carbene ligand are used to catalyze cross-metathesis reactions to provide a variety of substituted and functionalized olefins, including phosphonate-substituted olefins, directly halogenated olefins, 1,1,2-trisubstituted olefins, and quaternary allylic olefins. The invention further provides a method for creating functional diversity using the aforementioned complexes to catalyze cross-metathesis reactions of a first olefinic reactant, which may or may not be substituted with a functional group, with each of a plurality of different olefinic reactants, which may or may not be substituted with functional groups, to give a plurality of structurally distinct olefinic products. The methodology of the invention is also useful in facilitating the stereoselective synthesis of 1,2-disubstituted olefins in the cis configuration.

标 题:Preparation and use of (2-butene-1,4-diyl)magnesium complexes in organic synthesis

摘要:The magnesium complexes of cyclic hydrocarbons containing conjugated dienes, such as 1,2-dimethylenecycloalkanes, and 1,3-butadienes, are readily prepared in high yields using highly reactive magnesium. Reactions of these (2-butene-1,4 diyl)magnesium reagents with electrophiles such as dibromoalkanes, alkylditosylates, alkylditriflates, bromoalkylnitriles, esters, or amides serve as a convenient method for synthesizing carbocyclic systems. Significantly, carbocycles prepared by this method contain functional groups such as the exocyclic double bond or a keto group in one of the rings which could be used for further elaboration of these molecules. Furthermore, fused bicyclic systems containing a substituted five-membered ring can be conveniently prepared at high temperatures by the reactions of (2-butene-1,4-diyl)magnesium complexes with carboxylic esters or acid halides whereas low temperatures lead to regioselective synthesis of β,γ-unsaturated ketones. Additionally, γ-lactones, including spiro γ-lactones, can be easily prepared in a one pot synthesis from the reaction of (2-butene-1,4-diyl)magnesium complexes with a ketone or aldehyde and carbon dioxide. Also, δ-lactones can be easily prepared in a one pot synthesis from the reaction of (2-butene-1,4-diyl)magnesium complexes with epoxides followed by reaction with CO 2 . Use of α-hydroxy epoxides without the addition of CO 2 leads to the synthesis of vicinal diols. Chiral epoxides lead to chiral alcohols.
