Cobalt alkanoates

Unmodified Cobalt Process. Typical sources of the soluble cobalt catalyst include cobalt alkanoates, cobalt soaps, and cobalt hydroxide [1307-86 ] (see Cobalt compounds). These are converted in situ into the active catalyst, HCo(CO)4, which is in equihbrium with dicobalt octacarbonyl... 

Regioselective oxidation of 2- and 4-alkyl-l,4-hutanediols. 2,2-Disubstituted 1,4-butanediols (1) are oxidized by this combination -.electively to the 7-butyrolactones 2. Cobalt(II) alkanoates and trityl tetrafluoroborate show comparable selectivity. 

The hydrocarbohydroxylation of 1-alkenes is promoted by nickel, cobalt, platinum, and palladium catalysts to give linear and branched alkanoic acids in differing ratios (Eq. 46). Nickel catalysts, e.g., Ni(CO)4, NiCE, NH2 and... 

Polynuclear complex salts of chromium, aluminum, iron and cobalt are reported to have been used to form the alignment layers for liquid crystalline materials [2-3]. In Fig. 3.7.2 are the structures of layers on glass surfaces treated by carboxylatochromium complexes of (a) an alkanoic acid and (b) an alkandioic acid. Glass surfaces treated by n-alkanoic acids with more than 3 carbon atoms induce homeotropic liquid crystalline alignment as indicated in Fig. 3.7.2(a). On the other hand. Fig. 3.7.2(b) shows the structure of glass surfaces treated by carboxylatochromium complexes of an alkandioic acid. These surfaces show homogeneous... 

The reaction of diketene with Grignard reagents in the presence of a cobalt catalyst provides a convenient method for the synthesis of 3-methylene-alkanoic acids. These methods have also been applied to the synthesis of keto-acids and hydroxy-acids. ...
