Latest Patents
Ziegler's latest patents include a dental material containing phosphonic acids. This invention relates to dental materials that incorporate hydrolysis-resistant phosphonic acids with ethylenically unsaturated double bonds, making them particularly suitable as adhesion promoters. Another notable patent is a method of producing aryl-substituted, amino-acylated phosphonic-acid derivatives. This method utilizes metal complexes of chiral amphiphilic ligands, allowing for the asymmetric hydrogenation of .alpha.-N-acyl-protected, .beta.-substituted alkene phosphonic derivatives in the presence of a chiral rhodium catalyst. The use of a micelle-forming catalyst enables the hydrogenation of unsaturated phosphonic-acid derivatives in water, achieving high reaction rates and excellent enantiomeric excesses.
