The invention discloses a method for preparing a moth pheromone pickles, characterized in that comprises the following steps: S1, taking eleven vinyl alcohol synthesis undecene - 11 - ol benzoates; S2, will take Hendecane glycol synthesis Hendecane mono benzoates; S3, synthetic undecanal - 11 - ol benzoates; S4, synthetic cis - 11 - hexadecenoic - 1 - ol benzoates; S5, synthetic cis - 11 - hexadecenoic - 1 - ol; S6, synthetic cis - 11 - sixteen [...]; S7, synthetic cis - 11 - hexadecenoic - 1 - ethoxylate ester; S8, the composition is mixed, moth pheromone shall pickles. The present invention, adopts a double-sodamide as alkali, phosphine ye li? deodorant pentane as raw material with undecanal - 11 - alcohol benzoate reaction occurs, the reaction yield is as high as 89%, and syn-form isomer content of 98% or more, and the synthetic method is simple.

Room temperature ambient pressure (RTAP)-hydroformylation in water using a self-assembling ligand

We herein demonstrate a hydroformylation at room temperature and ambient pressure (RTAP) using our Rh/6-DPPon (1) system in aqueous media. The hydrogen bonding network of the ligand backbone stays intact, exemplified by the excellent regioselectivity for the linear aldehyde. Various substrates with different functional groups (with some prone to hydrolysis) are stable under the applied conditions and can undergo hydroformylation resulting in good yields. Copyright
Preparation of a Polymer-supported Diol and Its Use in isolating Aldehydes and Ketones from Mixtures and as a Protecting Group for Aldehydes and Ketones

Reaction of cross-linked chloromethylated polystyrenes with 3-mercaptopropane-1,2-diol and sodium hydroxide under phase-transfer conditions gave polymers containing diol residues.A range of aldehydes and ketones were successfully bound to these polymers via acetal formation.The aldehydes and ketones were released by treating the products with aqueous dioxane in the presence of toluene-p-sulphonic acid.The polymer-supported diol could be used to isolate aldehydes or ketones from mixtures with other compounds and to separate a 3-oxosteroid from a 17- or a 20- oxosteroid.The supported diol was successfully used to protect the aldehyde group of undec-10-enal whilst the terminal vinyl group was transformed into -CH2CH2OCOPh.Attempts to monoprotect dicarbonyl compounds were unsuccessful.
