The acetal formation mechanism under acid-free Rh-catalyzed hydroformylation-acetalization condition has been studied using different rhodium catalyst precursors in MeOH. In the absence of added acidic co-catalyst, the ace-talization is catalyzed by the H~+ formed in situ under hydroformylation ...

formation of an acetal. The importance of acetals as carbonyl derivatives lies in their stability and lack of reactivity in neutral to strongly basic environments. As long as they are not treated by acids, acetals exhibit all the lack of reactivity associated with ethers in general. If the ...

3->5, 6->7 are both in the acetal mechanism (the lewis acid changes, but the mechanism doesn't). 5->6 is a variation of the aldol.7->8 starts with a variation of imine formation, then joins 8->9 as a variation of a Michael addition.Lots of variations of common reactions... ...
organisations such as Pegida and sometimes are even personally willing to violently persecute Muslims. At the same time, it also sheds light on why some Muslims support London bombings and the 9/11 attacks, and personally engage in terror against the West or even go abroad to fight for other...

The finding that the TO/DO/TOP system having a relatively high amount of cyclic formals consumed in the copolymerization exhibited a relatively low thermal stability suggested that the transacetalization reactions proceeded mainly via oxocarbenium species other than cyclic oxonium species, as compared ...

These pathways are crucial for the formation of initial C-C bonds, hydrocarbon pools, and coke precursors. Common oxygenates involved in the reaction include acids, aldehydes/ketones, and their methylated derivatives (esters, acetals/ketals). Despite their lower abundance, oxygenates significantly ...
