权利人:ASM IP HOLDING BV
摘要:Disclosed are methods and systems for forming a silicon-containing layer on a substrate. Further disclosed are composition and synthesis of silicon-containing precursor. The methods for forming a silicon-containing layer comprise executing a plurality of deposition cycles. A deposition cycle comprises a first precursor pulse that comprises exposing the substrate to a first precursor. The first precursor comprises a molecule comprising a P—Si bond. A deposition cycle further comprises a plasma pulse that comprises exposing the substrate to a plasma treatment. The plasma treatment comprises generating a plasma.

标 题:Preparation of P-chirogenic phospholanes and their use in asymmetric synthesis
发明人：HOGE II GARRETT STEWART
权利人:PFIZER
摘要:Materials and methods for preparing P-chirogenic monophospholanes and bisphospholanes are disclosed. The methods employ stereoselective cyclization to generate the phospholane rings followed by pyramidal inversion to access a variety of P-chirogenic phospholanes. When bound to transition metals such as rhodium, the disclosed P-chirogenic phospholanes may be used as catalysts in asymmetric synthesis of valuable pharmaceutical chemical entities, including pregabalin.

标题:Asymmetric synthesis catalyzed by transition metal complexes with rigid chiral ligands
发明人：ZHANG XUMU
权利人:PENN STATE RES FOUND
摘要:This invention is to develop novel transition metal catalysts for the practical synthesis of important chiral molecules. The invention emphasizes asymmetric catalysis based on chiral bidentate phosphine ligands with cyclic ring structures which could be used to restrict conformational flexibility of the ligands and thus the efficiency of chiral transfer can be enhanced through the ligand rigidity.

摘要:P-chirogenic organophosphorus compounds of general formula (I), a process for the synthesis of the compounds of formula (I), and intermediate products of general formulae (II), (III) and (IV), as shown below, are involved in the synthesis of compounds (I). n n n n n n n n n n Metal complexes comprising compounds (I) as ligands are also described. The compounds and complexes are useful in asymmetric catalysis by transition metal complexes or organocatalysis, especially for asymmetric hydrogenation or allylation. Compounds of general formula (I) may be useful as agrochemical and therapeutic substances, or as reagents or intermediates for fine chemistry.
