The knights who say Ni: A practical and convenient synthetic route to fattyacids involves the Ni‐catalyzed alkylalkyl cross‐coupling of bromoalkanoicacids and alkylGrignardreagents in the presence of 1,3‐butadiene as an additive (see scheme).
The present invention provides a device for modifying an atmosphere in proximity to the device, the device comprising a sachet comprising a semipermeable material, and a composition including a mixture of acetylsalicylic acid and sodium bicarbonate contained within a cavity of the sachet. The invention further provides methods for modifying an atmosphere comprising placing a mixture of a carboxylic acid and a base in the atmosphere, wherein the atmosphere has a sufficient level of water vapor such that, upon contact of the water vapor with the mixture, carbon dioxide is produced.
A method and means for enhancing the inner environment of a package containing perishable merchandise include taking a closable package containing perishable merchandise and placing in the package a multi-layered sheet including a plurality of layers comprised of moisture absorbing materials to absorb any residual moisture emanating from the perishable merchandise. The multi-layered sheet includes a quantity of CO
