Paragraph 0052; 0071, (2020/01/24)
This invention relates to gels that undergo either oscillatory stepwise expansion or oscillatory expansion and contraction. An oscillatory reaction occurs within the gel, changing the conditions of the gel, and causing the gel to expand and optionally con

Oxidative carbonylation of alkynes can be carried out catalytically in the absence of added oxidants if it is coupled with a reductive carbonylation process at the expense of the same alkyne involved in the oxidative process.Maleic esters (from oxidative carbonylation) and unsaturated lactones (from reductive carbonylation) are the main products formed under the catalytic action of palladium iodide complexes with thiourea (tu).A complex, formally corresponding to the ionic formula I, allows the reaction of alkylacetylenes at room temperature and atmospheric pressure.With activated alkynes such as phenylacetylene, or with alkynes containing coordinating groups, other palladium complexes with two or four molecules of thiourea are also active, although to a lesser extent.Identification of the organic by-products gives a hint of the mechanism by which coupling of oxidative and reductive carbonylation occurs.Keywords: Palladium; Alkynes; Oxidative carbonylation; Reductive carbonylation; Catalysis, Thiourea

Terminal alkyne dicarbonylation can be readily effected under mild conditions by treating alkynes with carbon monoxide and alcohols or water at 25-80 deg C in the presence of PdI2, KI and air, with unprecedented catalytic efficiency.Dicarbonylation products are mainly maleic esters or acids and their ring-chain tautomers.The latter are formed to a large extent at room temperature.Reaction pathways are discussed.
