Abstract
Abstract The (ether-phosphane) ligands R2PCH2(1,4-diox) (1a–c) (R = Ph (a), Mes (b), Cy (c); diox = dioxane residue) and Ph2PCH2(1,3-diox) (2a) are obtained from the corresponding phosphides LiPR2 and 2-chloromethyl-1,4-dioxane and −1,3-dioxane, respectively, at −40°C in ether. High pressure experiments can provide useful information on conversion and selectivity in the (hydro)carbonylation of methanol, if parameters like educt/catalyst ratio, effect of substituents of the ligands 1a–c, 2a, directed application of cobalt complexes, and composition of catalyst and synthesis gas are varied. The possibility that there is a cobalt-catalyzed (hydro)carbonylation of methanol to acetaldehyde and acetic acid cycle is explored.
