Methylcyclopentadiene is any of three isomeric cyclic dialkenes with the formula C 5 MeH 5 (Me = CH 3).These isomers are the organic precursor to the methylcyclopentadienyl ligand (C 5 H 4 Me, often denoted as Cp′), commonly found in organometallic chemistry.
Hydroboration–oxidation is an anti-Markovnikov reaction, with the hydroxyl group attaching to the less-substituted carbon. The reaction thus provides a more stereospecific and complementary regiochemical alternative to other hydration reactions such as acid-catalyzed addition and the oxymercuration–reduction process.
Paul was also critical of the National Institutes of Health spending $1,513,299 since 2019 on experiments where kittens are strapped to a hydraulic table that tilts and spins in all directions in ...
Cyclopentene was first prepared by Carl Gärtner in 1893 from iodocyclopentane with potassium hydroxide.He named it pentamethenylene (German: Pentamethenylen). [3] ...

Catalyzed hydroboration-oxidation of substituted alkenes can be rendered enantioselective. In 1990, Brown and co-workers achieved asymmetric hydroboration using an achiral catalyst and chiral borane sources derived from ephedrine and pseudoephedrine. In most cases, the regioselectivity was poor although the ee values can be close to 90%. [16]
Lentigo in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins. Unlike in ...
It is one of many products from the pyrolysis of lignocellulose. [4]It is used in flavors and perfumery for its maple- or caramel-like odor. [5] It contributes to the flavor or odor of many foods including wines, coffee, paprika, and salmon.
