Synthetic method for preparing isododecanol polyoxyethylene ether from hexyl alcohol

The invention relates to a synthetic method for preparing isododecanol polyoxyethylene ether from hexyl alcohol. The invention belongs to the technical field of synthesis of nonionic surfactants in organic chemistry. The synthetic method comprises the following steps: (1) by using hexyl alcohol as an initiator, adding a catalyst under the protection of nitrogen to carry out aldol condensation reaction, thereby obtaining isododecanol; and (2) under the action of a catalyst, carrying out an induction reaction on the isododecanol prepared in the step (1) and part of ethylene oxide, and carrying out a polymerization reaction on the remaining ethylene oxide to obtain the isododecanol polyoxyethylene ether.

Diastereoselective synthesis of functionally substituted alkene dimers and oligomers, catalysed by chiral zirconocenes

The research addresses the reaction of terminal alkenes and propene with AlR3 (R = Me, Et) in the presence of chiral Zr complexes, rac-[Y(η5-C9H10)2]ZrCl2 (Y = C2H4, SiMe2) or (NMI)2ZrCl2 (NMI- η5–neomenthylindenyl), and methylaluminoxane. The effect of reaction conditions, catalyst and trialkylalane structure on the substrate conversion and the reaction chemo- and stereoselectivity has been studied. The reaction predominantly goes via the stage of alkene methyl(ethyl)zirconation with subsequent introduction of substrate molecules into the Zr-C bond. As a result, a diastereoselective one-pot method for the synthesis of functionally substituted linear terminal alkene dimers and propene oligomers was developed.
