... studied Rh catalyzed reaction pathways exhibited singlet ground state, as ruthenium homologous mechanism [50,65–68], but differently with respect to iron [42,43]. However, here the rhodium center might be disproportionate, or lose one chloride, like Castarlenas et al. have recently demonstrated [53] ...

Excited State Reactions of Carbonyl Compounds
... are polarized in such a way that the carbonyl carbon is positively polarized. Most reactions of the carbonyl chromophore in the ground state can be understood on the basis of this simple model. The non-bonding lone pair present on the oxygen is nucleophilic, and many electrophilic reactions with the ...

Novel Transition Metal-Catalysed Syntheses of Carboxylic Acid
... The largest category of such reactions features the ruthenium metathesis catalysts developed by Grubbs and co-workers.[14] These alkylidene complexes are truly remarkable in terms of scope of their activity, so much so that an account of their nonmetathetic reactions has been recently published.[15] ...

... In fact, when R3 C-Br has fewer than two CH3 groups, it does not react at all by the S N1 mechanism (see Figure7.13). These changes in SN1 rates result from the effect of alkyl groups such as CH3 on the stability of R3 C+ that forms in the first step of the SN1 mechanism. Carbocation Stability. The ...

Cracking (chemistry)
In petroleum geology and chemistry, cracking is the process whereby complex organic molecules such as kerogens or heavy hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts. Cracking is the breakdown of a large alkane into smaller, more useful alkanes and alkenes. Simply put, hydrocarbon cracking is the process of breaking a long-chain of hydrocarbons into short ones. More loosely, outside the field of petroleum chemistry, the term ""cracking"" is used to describe any type of splitting of molecules under the influence of heat, catalysts and solvents, such as in processes of destructive distillation or pyrolysis. Fluid catalytic cracking produces a high yield of petrol and LPG, while hydrocracking is a major source of jet fuel, Diesel fuel, naphtha, and again yields LPG.
