Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 97739-46-3, is researched, Molecular C16H21O3P, about Pd-Catalyzed Regioselective Alkoxycarbonylation of 1-Alkenes Using a Lewis Acid [SnCl2 or Ti(OiPr)4] and a Phosphine, the main research direction is alkene alc carbon monoxide palladium Lewis acid phosphine alkoxycarbonylation; ester regioselective preparation.Safety of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane.
The phosphine ligand mediated palladium catalyzed alkoxycarbonylation of alkenes was investigated with the objective of attaining good linear selectivity for the ester. The effect of various parameters such as solvents, additives, palladium precursors, CO pressures, and alkenes of various structural complexities were examined The results revealed the importance of using a Lewis acid such as SnCl2 or Ti(OiPr)4 in combination with a monodentate ligand such CYTOP 292 or P(p-anisyl)3 to enhance the regioselectivity for the linear isomers in the range of 70-96%.
This literature about this compound(97739-46-3)Safety of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantanehas given us a lot of inspiration, and I hope that the research on this compound(1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane) can be further advanced. Maybe we can get more compounds in a similar way.
