Recyclable Ligand‐free Cobalt Catalyst for Alkoxycarbonylation of Chloroacetates

ChemSusChem, Accepted Article.
Direct carbonylation of the C(sp3)‐Cl bond remains a challenging transformation in the chemical industry. The usual use of precious metals, the high cost of ligands and the lack of recyclability of catalysts make their industrial application on a large scale impossible.

Effects of Concurrent Sulfur and Phosphorus Incorporation in Nickel Cyclam‐Based Complexes

European Journal of Inorganic Chemistry, EarlyView.
The concurrent incorporation of phosphorus and sulfur into cyclam is investigated by the synthesis of the P, S, N‐containing 14‐membered macrocycles and their corresponding nickel complexes, which exist in both square‐planar and octahedral geometries.

Microemulsions with Alkyldimethyl Phosphine Oxides and Alkyldiethyl Phosphine Oxides

Langmuir, 2008
Alkyldimethyl phosphine oxides (C n DMPO) as well as alkyldiethyl phosphine oxides (C n DEPO) with chain lengths of n = 10 (decyl), 12 (dodecyl), and 14 (tetradecyl) were synthesized and purified to study how the formation of microemulsions depends on the size of the headgroup and on the length of the alkyl chain.

Reduction of phosphine oxides to phosphines

Tetrahedron Letters, 2019
Abstract The digest is devoted to the most widespread reducing agents which are used for the reduction of tertiary and secondary phosphine oxides, phospholene oxides, phospholane oxides, phosphonates, phosphinates, α- and β-hydroxy and thiomethyl phosphine oxides, α-aminophosphine oxides. Stereoselectivity of reactions is described.
