Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, ChemCatChem called An empirical study of phosphine ligands for the methoxycarbonylation of medium-chain alkenes, Author is Holzapfel, Cedric; Bredenkamp, Tyler, which mentions a compound: 97739-46-3, SMILESS is CC1(C2)OC(C3)(C)OC2(C)OC3(C)P1C4=CC=CC=C4, Molecular C16H21O3P, Computed Properties of C16H21O3P.
The methoxycarbonylation reaction provides a route to the synthesis of esters from medium-chain alkenes that may be used as fuel supplements. However, the known productive catalytic systems are expensive and/or unstable at elevated temperatures Most of the data available on the methoxycarbonylation of alkenes is derived from ethylene and styrene as substrates. To broaden the scope, we conducted a comparative study of a range of phosphine ligands under comparable conditions for the methoxycarbonylation of 1-octene. The results demonstrate that a number of ligand structural motifs facilitate the process effectually. Furthermore, the critical importance of alkene isomerization and the acid/ligand and Pd/ligand ratios are presented.
