Abstract

Lub thermal unimolecular decomposition ntawm peb vinylethers tau kawm nyob rau hauv ib tug VLPP apparatus. Qhov siab-siab tus nqi tas mus li rau cov tshuaj tiv thaiv retro-ene ntawm ethylvinylether yog haum los ntawm log k (sec−1)=(11.47 ntxiv rau 0.25) - (43.4 ± 1.{12} })/2.303 RT ntawm{{0}} K thiab ntawm t - butylvinylether los ntawm log k (sec−1)=(12.00 ± 0.27) - (38.4 ± 1.0)/2.303 RT NWS at{{0}} K. Tsis muaj pov thawj rau kev sib tw ntawm lub zog siab dua homolytic bond-fission txheej txheem tuaj yeem tau txais los ntawm cov ntaub ntawv sim. Tus nqi tsis tu ncua nrog CO daim ntawv cog lus scission cov tshuaj tiv thaiv nyob rau hauv cov ntaub ntawv ntawm benzylvinylether yog log k (sec−1)=(16.63 ± 0.30) - (53.74 ± 1.0)/2.303 RT ntawm{{0}} K. Ua ke nrog ΔHf,30{{10}}}0(benzyl·)=47.0 kcal/mol, lub zog ua kom muaj zog rau qhov kev tshwm sim no tshwm sim hauv ΔHf,3000(CH2CHO)=ntxiv rau 3.0 ± 2.0 kcal/mol thiab ib qho kev sib raug zoo resonance stabilization zog ntawm 3.2 ± 2.0 kcal / mol rau 2-ethanalyl radical.
