An efficient and commercial phosphorylation process of a complex alcohol, such as secondary and tertiary alcohols, with P4O10 at high temperatures, and a product obtained by the process.
[Rh(acac)(CO)2] and [Mo(CO)6] showed the highest activity and was therefore applied to the reduction of lactones to diols. The reduction potential of the catalyst was found to be dependent on the ring size of the lactone used. Five-membered ring lactones were hardly converted to diols whereas six- and seven- membered ring lactones reacted easily.
A resin composition for insulating coating material, comprises: a polyimide resin and/or a precursor thereof; and a polymer having a heterocyclic ring at a side chain, wherein the content of the polymer having a heterocyclic ring at a side chain is 0.1 to 7 parts by weight relative to 100 parts by weight of the polyimide resin and/or the precursor thereof. By adding a prescribed amount of the polymer having a heterocyclic ring at a side chain, there can be obtained a resin composition for insulating coating material still maintaining heat resistance and together having excellent bending resistance.
