Paragraph 0140-0144, (2021/01/29)
PROBLEM TO BE SOLVED: To provide a ruthenium complex that is particularly useful as a catalyst for oxidizing a substrate having a carbon-hydrogen bond. SOLUTION: The ruthenium complex represented by the general formula (i) or a cis conformer thereof is provided. In the general formula (i), R1 represents H, a phenyl group or a substituted phenyl group; R2 represents H, a phenyl group or an alkyl group; L1 represents halogen or water molecule; L2 represents triphenylphosphine, pyridine, imidazole or dimethylsulfoxide; X represents halogen; and n represents 1 or 2.

Insertion of CO2 into the polyacrylate backbone, forming poly(carbonate) analogues, provides an environmentally friendly and biocompatible alternative. The synthesis of five poly(carbonate) analogues of poly(methyl acrylate), poly(ethyl acrylate), and poly(butyl acrylate) is described. The polymers are prepared using the salen cobalt(III) complex catalyzed copolymerization of CO2 and a derivatized oxirane. All the carbonate analogues possess higher glass-transition temperatures (Tg=32 to ?5 °C) than alkyl acrylates (Tg=10 to ?50 °C), however, the carbonate analogues (Td≈230 °C) undergo thermal decomposition at lower temperatures than their acrylate counterparts (Td≈380 °C). The poly(alkyl carbonates) exhibit compositional-dependent adhesivity. The poly(carbonate) analogues degrade into glycerol, alcohol, and CO2 in a time- and pH-dependent manner with the rate of degradation accelerated at higher pH conditions, in contrast to poly(acrylate)s.

Paragraph 0048; 0049, (2016/12/16)
PROBLEM TO BE SOLVED: To provide a production method with which α-acyloxy acrylate can be obtained at high yield using commodity chemicals as raw materials and which is thereby suitable to be used industrially as a method for producing the α-acyloxy acrylate. SOLUTION: The method for producing the α-acyloxy acrylate includes a process for obtaining the α-acyloxy acrylate, which has a specific structure, using glycidic esters that have a specific structure.
