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]
1,2,3,4,5-Pentakis(4-butylphenyl)-1,3-cyclopentadiene is an organochemical compound from the diene group and a cyclopentadiene derivative. The anion of this compound is used as a sterically demanding ligand, often abbreviated as Cp [BIG] , in the organometallic chemistry of sandwich compounds .
C 6 H 6 + C 2 H 4 → C 6 H 5 C 2 H 5. The diethylbenzene is an inadvertent side product. C 6 H 5 C 2 H 5 + C 2 H 4 → C 6 H 4 (C 2 H 5) 2. Using shape-selective zeolite catalysts, the para isomer can be produced in high selectivity. Much diethylbenzene is recycled by transalkylation to give ethylbenzene: [1] C 6 H 4 (C 2 H 5) 2 + C 6 H 6 → ...
1,4-Pentadiene can be prepared from 1,5-pentadiol via the diacetate. [6] 1,3-Pentadiene, like 1,3-butadiene, undergoes a variety of cycloaddition reactions. For example, it forms a sulfolene upon treatment with sulfur dioxide. [7]
Typical examples of this type of complex are group 14 metal complexes such as CpSiMe 3. An example of both is (Cp 2 Fe(CO) 2). It is probable that η 1-Cp complexes are intermediates in the formation of η 5-Cp complexes. Still rarer, the Cp unit can bond to the metal via three carbons. In these η 3-Cp complexes, the bonding resembles that in ...
[3] These correlation diagrams indicate that only a conrotatory ring opening of 3,4-dimethylcyclobutene is symmetry allowed whereas only a disrotatory ring opening of 5,6-dimethylcyclohexa-1,3-diene is symmetry allowed. This is because only in these cases would maximum orbital overlap occur in the transition state. Also, the formed product ...
[2] [1] Illustrative of the unusual complexes made possible with these bulky ligands is molecular iron nitrido complex ( t Bu 3 C 5 H 2 ) 2 Fe 2 N 2 . [ 3 ] In contrast to (C 5 Me 5 ) 2 Ir 2 Cl 4 , ( t Bu 3 C 5 H 2 )IrCl 2 is monomeric.
Ethylbenzene is an organic compound with the formula C 6 H 5 CH 2 CH 3.It is a highly flammable, colorless liquid with an odor similar to that of gasoline.This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene, the precursor to polystyrene, a common plastic material.
