The liquid was concentrated in a rotary evaporator. The remaining solid was dissolved in PE/EA (19:1) (10 mL) and filtrated over silica (80 g) in a 40×2 cm column, eluting with 500 mL of PE/EA.
Webether, any of a class of organic compounds characterized by an oxygen atom bonded to two alkyl or aryl groups. Ethers are similar in structure to alcohols, and both ethers and alcohols are similar in structure to water. … WebTetrahydrofuran (THF) The common name of the cyclic ether "oxacyclopentane" is tetrahydrofuran, or THF. It is a common organic solvent that is miscible with water. Properties of Ethers Ethers are rather nonpolar due to the presence of an alkyl group on either side of the central oxygen.
In organic chemistry, ethers are a class of compounds that contain an ether group—an oxygen atom connected to two alkyl or aryl groups. They have the general formula R−O−R′, where R and R′ represent the alkyl or aryl groups. Ethers can again be classified into two varieties: if the alkyl or aryl groups are the … See more Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar.
