A sophisticated photoactive molecular device has been prepared by combining recent concepts for the preparation of multifunctional nanomolecules (click chemistry on multifunctional scaffolds) with supramolecular chemistry (self-assembly to prepare rotaxanes). Specifically, a clickable [2]rotaxane scaffold incorporating a free-base porphyrin stopper has been prepared and functionalized with ten peripheral Zn(II)-porphyrin moieties. Electrochemical investigations of the final compound revealed a peculiar behavior resulting from the intramolecular coordination of the Zn(II) porphyrin moieties to 1,2,3-triazole units. Finally, steady state investigations of the compound combining Zn(II) and free-base porphyrin moieties have shown that this compound is a light-harvesting device capable of channeling the light energy from the peripheral Zn(II)-porphyrin subunits to the core by singlet–singlet energy transfer.

A green and efficient method was developed for upgrading furfural to 1,10-decanediol diacetate and 1-decanol acetate. 92% yield of the acetates was obtained through the tandem benzoin condensation and hydrodeoxygenation reaction. During the benzoin condensation, furfural was catalyzed into furoin in a quantitative yield by the immobilized NHC catalyst under solvent-free conditions. After dissolving the furoin intermediate in acetic acid, the Sc(OTf)3and Pd/C catalytic system was introduced for hydrodeoxygenation. The effects of reaction factors have been investigated in detail and the hydrodeoxygenation process has been explored by1H-NMR and GC-MS.

-
Paragraph 0036-0038; 0068-0080, (2019/07/01)
The invention discloses a method for synthesizing 1,9-decadiene. The method sequentially comprises the following steps: adding carboxylic acid and 1,10-decadienol into a reaction container, heating the container until the 1,10-decadienol is dissolved, adding a catalyst, carrying out an esterification reaction at 120-200 DEG C, and collecting water evaporated in the esterification reaction; continuously heating the container to 300-350 DEG C after no water is produced in the esterification reaction, carrying out a reaction for 5-8 h, and evaporating and collecting a mixed solution of 1,9-decadiene and carboxylic acid; and respectively post-processing the mixed of 1,9-decadiene and carboxylic acid to obtain carboxylic acid and 1,9-decadiene respectively. The method for preparing 1,9-decadiene is efficient, economical and green, and meets industrial production requirements.
Molecular iodine in isopropenyl acetate (IPA): a highly efficient catalyst for the acetylation of alcohols, amines and phenols under solvent free conditions
Ahmed, Naseem,van Lier, Johan E.
, p. 5345 - 5349 (2007/10/03)
Iodine in isopropenyl acetate (IPA) is a highly efficient catalyst for the acetylation of a variety of alcohols, phenols and amines under solvent free conditions. Primary, secondary, tertiary alcohols, amines and mono to polyhydroxy phenols and anilines with electron donating or withdrawing substituents can be easily acetylated in good to excellent yield at 85-90 °C.
Process for preparing monoesters
-
Page/Page column 5, (2008/06/13)
A process for preparing monoesters comprises the step of reacting at least one diol with at least one carboxylic acid in a biphasic solvent system, the carboxylic acid being sufficiently water soluble to allow esterification to occur, and the biphasic solvent system comprising water and at least one aprotic solvent in which the resulting monoester has greater solubility than in water.
