The invention relates to azaphospholenes of the type ##STR1## wherein R.sub.1 and R.sub.2 may be alkyl, aryl and aralkyl groups, processes for preparing same and the use thereof.

Azaphospholenes and use thereof

The invention relates to azaphospholene of the type ##STR1## wherein R.sub.1 and R.sub.2 may be alkyl, aryl and aralkyl groups, processes for preparing same and the use thereof.

The invention relates to a process for the dimerization of derivatives of acrylic acid in the homogeneous phase which process is characterized in that a compound having the general formula H.sub.2 C.dbd.CR.sup.1 -COOR.sup.2, wherein R.sup.1 represents H or a linear alkyl group having from 1 to 3 carbon atoms and R.sup.2 represents a linear alkyl group having from 1 to 3 carbon atoms, is reacted in a solvent at a temperature of from -50.degree. C. to +50.degree. C. in the presence of nickel compounds as catalysts which contain complex anions X in a molar ratio Ni:X=1:1 and organic or hydride ligands and are modifed with phosphanes having the general formula PR.sub.2 R', wherein R and R' may be same or different and represent alkyl residues having from 1 to 8 carbon atoms or phenyl residues, as well as the use of the dimers formed in the dimerization.

Process for catalytic dimerization of acrylic acid derivatives

Optically active compounds are prepared from optically inactive unsaturated hydrocarbons by reacting at least one unsaturated hydrocarbon in the presence of a catalyst prepared by combining a nickel compound, a Lewis acid and an optically active phosphine of the general formula

Optically active cyclooctenyl ethyl alcohol

Optically active 3-methyl-pentene-1

Complexes of nickel or cobalt with phosphine, phosphite, stilbene or arsine ligands, especially nickel-phosphine complexes, useful as catalysts.

Metal complexes

Process for reacting an H-acidic organic compound, in which the acidic H-atom is bonded to the organic radical by an oxygen or a sulphur atom, e.g. an alcohol, with a metal having a standard potential which is more positive than -1.66 volts and which at most incompletely reacts with the H-acidic compound under current-free conditions, e.g. Ni, Co, Fe, Mn, Sb, Cu, or Au. The H-acidic compound or a solution thereof is a polar solvent is made conducting by addition of a soluble salt of chlorine, bromine or iodine, and is electrolyzed at a temperature of up to 150.degree. C, using said metal as the anode, for production of the alcoholate.

Process for the electrochemical synthesis of organic metal compounds

Optically active 3-substituted cyclooctene bicyclo-[6.0.3.]-undecene-3

Process of producing nickel alcoholates by reacting .pi.-allyl nickel compounds with carbonyl compounds. The nickel alcoholates so produced can be hydrolyzed to their corresponding alcohols and these alcohols can in part be dehydrated to their corresponding olefins. The nickel alcoholate products are useful for the production of their corresponding alcohols and these alcohols are useful for the production of their corresponding olefins.

Phenyl substituted-hexene-(3)-diol-(1,6)

A series of mono, bi and tricarbocyclic compounds, most of which have olefinic unsaturation in the ring, which may or may not have substituents thereon. While the bi and tricyclic rings may be unsubstituted, these compounds which have olefinic unsaturation, particularly multiple olefinic unsaturation, are polymerizable and copolymerizable in known polymerization systems. They are particularly good crosslinking agents. These compounds are further useful in the sense that they can be cleaved oxidatively, to corresponding carboxylic acids, aldehydes and/or alcohols which have known utility in the plasticizer and detergent arts. The compounds which do not have olefinic unsaturation can also be oxidatively cleaved to produce oxygenated, e.g., acid, alcohol or aldehyde, compounds having known utility.

3-Methoxycyclooctadiene-(1,5)

1-Phenyl-cyclooctadiene (1,5)

3-Buten-1-yl (3) and 3 buten-2-yl (1) cyclooctadiene (1,5)

Ethyl 3,7-cyclodecadiene-1-carboxylate

This invention relates to novel nickel alcoholates and alcohols thereof and to a process of preparing said novel nickel alcoholates and alcohols.
