cis‐but‐2‐ene‐1,4‐diones3(2H)‐furanonesstereoselective oxidationtriphenylfuransTriphenylfurans are stereoselctively oxidized to cis‐but‐2‐ene‐1,4‐diones, suitable precursors of 3(2H)‐furanones, in very good yields using ammonium nitrate or potassium nitrate in 80% aqueous acetic ...
To solve the problem of determining the major product of the bromination of cis-but-2-ene in CCl4, we can follow these steps:Step 1: Understand the structure of cis-but-2-ene Cis-but-2-ene has the following structure:

To determine which statement is incorrect for cis-but-2-ene relative to trans-but-2-ene, we need to analyze the properties of both isomers based on their molecular structure and how this affects their physical properties.1. Identify the
Benzene molecules with fluoro- and trifluoromethyl-substituents have been used to sensitize the cis–trans isomerization of but-2-ene in the gas phase at 25 °C and various exciting wavelengths. For most compounds studied, the decay ratio of the olefin triplet to cis- and trans-ground-states ...
and -but-2-ene oxides undergo SN2 opening with the lithium enolate derived from [(η5-C5H5)Fe(CO)(PPh3)COCH2CH3] in the presence of BF3·OEt2; preferential opening occurs where the enolate configuration at iron matches that of the epoxide carbon being attacked.DOI...
