Novel unsaturated ethers were synthesized from sucrose using a mild two-step Gassman method. These monomers were polymerized into soluble polymers with pending sucrose groups, demonstrating potential for new material development.
Area of Science:
- Organic Chemistry
- Polymer Science
Background:
- Sucrose is an abundant, renewable carbohydrate source.
- Developing efficient synthetic routes to functionalized sucrose derivatives is of interest for novel polymer applications.
Purpose of the Study:
- To synthesize novel unsaturated ethers derived from sucrose.
- To polymerize these monomers and characterize the resulting polymers.
Main Methods:
- A two-step synthesis involving mixed acetal formation and subsequent elimination using trimethylsilyl trifluoromethanesulfonate and alkyl amines (Gassman method).
- Free radical polymerization of the synthesized sucrose-based unsaturated ethers.
- Characterization of polymer properties.
Main Results:
- Novel unsaturated ethers were synthesized in good yields.
- The monomers were successfully polymerized via a free radical mechanism.
- Unbranched, linear, and soluble polymers with pendant sucrose moieties were obtained.
Conclusions:
- The Gassman method provides an efficient route to sucrose-based unsaturated ether monomers.
- These monomers can be polymerized to yield well-defined, soluble polymers.
- The resulting polymers possess unique structures with potential for various applications.

02:29Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

02:28Structure and Nomenclature of Ethers
Ethers are organic compounds with an ether functional group which is characterized by an oxygen atom connected to two — identical or different — alkyl, aryl, or vinyl groups. The C–O–C linkage in dimethyl ether — the simplest ether — has an approximately tetrahedral bond angle of 110.3 degrees. The oxygen atom is sp3- hybridized, with the C–O distance being about 140 pm.

Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...
