-
Paragraph 0081; 0083; 0084, (2018/09/21)
The invention discloses a synthesis method of a terminal olefin type compound. The synthesis method comprises the following steps: taking a phosphorus ylide compound as a raw material and carbon dioxide as a C1 synthon in an organic solvent; reacting in the presence of a reducing agent to prepare the terminal olefin type compound, wherein the mole ratio of the phosphorus ylide compound to the reducing agent is 1 to (1 to 6) and the pressure of carbon dioxide is 1 to 3atm. The synthesis method disclosed by the invention has the advantages of convenience for operation, moderate conditions, widesubstrate applicable range and high efficiency; the defects in the prior art are filled; the synthesis method takes the carbon dioxide as synthon and carbon dioxide can be effectively absorbed so thata greenhouse effect is effectively prevented.
Thermal retro-aldol reaction using fluorous ether F-626 as a reaction medium

experimental part, p. 2193 - 2196 (2010/10/21)
A high-boiling, fluorous-organic hybrid ether, F-626, was tested for use in thermal retro-aldol reactions and found to be an excellent reaction medium in view of the ease of separation from the product by fluorous/organic biphasic treatment. The recovered F-626 can be readily reused for subsequent runs.

A novel approach for the synthesis of cis/trans-fused perhydroazulenes 13-19 is reported. The stereochemistry of the derivatives of carbene addition products 9a-c/20-22, of the 2,6-disubstituted perhydroazulenes 12a-c/23-25, and that of compounds 26-27 has been studied by single-crystal X-ray crystallography. The hydrogenation of the tropylidene to the perhydroazulene skeleton under various conditions is described. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
