Cyclopentadiene is a highly reactive diene in the Diels–Alder reaction because minimal distortion of the diene is required to achieve the envelope geometry of the transition state compared to other dienes. [11] Famously, cyclopentadiene dimerizes. The conversion occurs in hours at room temperature, but the monomer can be stored for days at ...
The molecular formula C 5 H 6 (molar mass: 66.10 g/mol, exact mass: 66.04695 u) may refer to: Cyclopentadiene; Cyclopropylacetylene [1.1.1]propellane;
Well known derivatives containing pentadiene groups include hexadienes, cyclopentadiene, and especially three fatty acids linoleic acid, α-linolenic acid, and arachidonic acid as well as their triglycerides (fats).
1,2,3,4,5-Pentamethylcyclopentadiene is a cyclic diene with the formula C 5 (CH 3) 5 H, often written C 5 Me 5 H, where Me is CH 3. [3] It is a colorless liquid. [1]1,2,3,4,5-Pentamethylcyclopentadiene is the precursor to the ligand 1,2,3,4,5-pentamethylcyclopentadienyl, which is often denoted Cp* (C 5 Me 5) and read as "C P star", the "star" signifying the five methyl groups radiating from ...
Ferrocene is an organometallic compound with the formula Fe(C 5 H 5) 2.The molecule is a complex consisting of two cyclopentadienyl rings sandwiching a central iron atom. It is an orange solid with a camphor-like odor that sublimes above room temperature, and is soluble in most organic solvents.
Novo Nordisk's and Eli Lilly's weight loss drugs can cost over $1,000 for a month's supply, while compounded versions typically cost a few hundred dollars. The FDA needs more support, Califf said.
