Hydroxy- and alkoxycarbonylation reactions constitute important industrial processes in homogeneous catalysis. Nowadays, palladium complexes constitute state-of-the-art catalysts for these transformations. Herein, we report the first efficient platinum-catalysed alkoxycarbonylations of olefins including sterically hindered and functionalized ones. This atom-efficient catalytic transformation provides
A curing agent composition for a water-soluble phenol resin used to produce a mold, which comprises a branched ester compound that is derived from a carboxylic acid having a branched chain, and an alcohol, and has 5 to 13 carbon atoms.
A process for producing a mold, comprising a step of mixing refractory particles, a water-soluble phenol resin, and a curing agent composition comprising an ester compound, thereby yielding mixed sands, and a step of putting the mixed sands into an original pattern to shape the sands, wherein the refractory particles comprise reclaimed sands that are artificial sands produced by a fusion method in a proportion of 70% or more by weight, the curing agent composition comprises at least one selected from triethylene glycol diacetate, triethylene glycol, 3-phenylpropane-1-ol, and benzyl alcohol.
