WebApr 11, 2024 · Reaction of PVC with 2 equiv. of sodium formate in THF in the presence of (xantphos)RhCl affords excellent selectivity for hydrodechlorination along with complete PVC dechlorination, yielding polyethylene-like polymers. Higher catalyst loadings were necessary to activate PVC towards reduction in this case.
WebAug 15, 2024 · T H F is a polar aprotic solvent, that is, it can stabilize positive charges but not negative ones since it won't form hydrogen bonds with the help of any of its own … WebSn1 reactions depend on the stability of the cation formed when the Leaving group had left. So, since tertiary carbocations are most stable of the three will undergo Sn1 reaction easily. Order: Tertiary > Secondary > Primary Sn2 reactions depend on the fastness of the leaving group. The fastness depends on the Leaving group.
WebFirst, NaBH4 is not so reactive and the reaction is usually carried out in protic solvents such as ethanol or methanol. The solvent has two functions here: 1) It serves as the source of a proton (H +) once the reduction is complete. 2) The sodium ion is a weaker Lewis acid than the lithium ion and, in this case, the hydrogen bonding between the ...
