[2] Reactions. The dehydration of cyclopentanol produces cyclopentene: C 5 H 10 O → C 5 H 8 + H 2 O. References This page was last edited on 11 July 2024 ...
The glyoxylate reacted with 2,4-dimethyl-2-pentane with trans-2-phenylcyclohexanol as a chiral auxiliary. For even greater conformational control, switching from a phenyl to a trityl group gives trans-2-tritylcyclohexanol (TTC). In 2015, the Brown group published an efficient chiral permanganate-mediated oxidative cyclization with TTC. [18]
The enantioselective synthesis was accomplished by J. K. Whitesell by adding Pseudomonas fluorescens lipase to racemic trans-2-phenylcyclohexyl chloroacetate. [1] [2] This enzyme is able to hydrolyze the ester bond of the (−)-enantiomer but not the (+)-enantiomer.
Vaska's complex is the trivial name for the chemical compound trans-carbonylchlorobis(triphenylphosphine)iridium(I), which has the formula IrCl(CO)[P(C 6 H 5) 3] 2.This square planar diamagnetic organometallic complex consists of a central iridium atom bound to two mutually trans triphenylphosphine ligands, carbon monoxide and a chloride ion.
Suppose that trans-cis-trans-2,4,6-octatriene is converted to dimethylcyclohexadiene under thermal conditions. Since the substrate octatriene is a "4n + 2" molecule, the Woodward–Hoffmann rules predict that the reaction happens in a disrotatory mechanism.
1,2-Dichloroethylene or 1,2-DCE is the name for a pair of organochlorine compounds with the molecular formula C 2 H 2 Cl 2. The two compounds are isomers, each being colorless liquids with a sweet odor. It can exist as either of two geometric isomers, cis-1,2-dichloroethene or trans-1,2-dichloroethene, but is often used as a mixture of the two ...
Acrolein and malonic acid react in pyridine to give trans-2,4-pentadienoic acid with the loss of carbon dioxide. The Doebner modification of the Knoevenagel condensation entails the use of pyridine as a solvent with at least one of the withdrawing groups on the nucleophile is a carboxylic acid , for example, with malonic acid .
2,2,4,4-Tetramethyl-1,3-cyclobutanediol (CBDO) is an aliphatic diol. This diol is produced as a mixture of cis - and trans - isomers , depending on the relative stereochemistry of the hydroxyl groups.
