Paragraph 0058; 0060; 0061, (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.

A new transition-metal-free reductive deoxygenative olefination of phosphorus ylides with CO2, an abundant and sustainable C1 chemical feedstock, is described. This catalytic CO2 fixation afforded β-unsubstituted acrylates and vinyl ketones in good yields with broad scope and good functional group tolerance under mild reaction conditions. Cost-effective and easily handled polymethylhydrosiloxane was used as a reductant. Bis(silyl)acetal was proved to be the key intermediate in this reductive functionalization of CO2.

Laser flash photolysis of p-CF3 and p-Cl-phenylchloro diazirines produces the corresponding carbenes which react with acetone to produce easily detected ylids.The absolute rate constants of reaction of these carbenes with acetone, and the rate constants of reaction of the ylids with diethylfumarate have been determined.No reaction was found between these carbenes and simple esters or ethylene carbonate.
