标题:Unimolecular Reactions Of Isolated Organic Ions: The Chemistry Of The Oxonium Ions Ch3Ch2Ch2Ch2+o = Ch2 And Ch3Ch2Ch2Ch = O+ch3
摘要:Abstractthe Reactions Of The Metastable Oxonium Ions Ch3Ch2Ch2Ch2+o = Ch2 And Ch3Ch2Ch2 = O+ Ch3 Are Reported And Discussed. Both These Isomers Of C5H11O+ Expel Predominantly Ch2O (75-90% Of The Metastable Ion Current),A Moderate Amount Of C3H6 (5-15%),A Minor Amount Of Ch3Oh (2-8%) And A Very Small Proportion Of H2O (0.5-3%). All These Processes Give Rise To Gaussian Metastable Peaks. The Kinetic Energy Releases Associated With Fragmentation Of These Oxonium Ions Are Similar,But Slightly Larger For Dissociation Of Ch3Ch2Ch2Ch = O+ch3. The Behaviour Of Labelled Analogues Confirm That The Reactions Of Ch3Ch2Ch2Ch = O+ch3 Are Closely Related,But Subtly Different. Elimination Of Ch2O And C3H6 Is Intelligible By Means Of Mechanisms Involving Ch3Ch+ch2Ch2och3. This Open‐chain Cation Is Accessible To Ch3Ch2Ch2 +o = Ch2 By A 1,5‐h Shift And To Ch3Ch2Ch2‐ch = O+ch3 By Two Consecutive 1,2‐h Shifts (Or,Possibly,A Direct 1,3‐h Shift). The Rates Of These 1,2‐,1,3‐ And 1,5‐h Shifts Are Compared With One Another And Also With The Rates Of Ch2O And C3H6 Loss From Each Of The Two Oxonium Ions. The 1,5‐h Shift That Converts Ch3Ch+ch2Ch2och3 Formed From Ch3Ch2Ch2Ch = O+ Ch3 Into Ch3Ch2Ch2+o = Ch2 Prior To Ch2O Elimination Is Essentially Unidirectional. In Contrast,The Corresponding Step Converting C5H11O+ Ions Generated As Ch3Ch2Ch2Ch2+o = Ch2 Into Ch3Ch+ Ch2Ch2och3 Competes Effectively With Expulsion Of Ch2O And C3H6. The Implications Of The Latter Finding For The Degree Of Concert In The Hydrogen Transfer And Carbon‐carbon Bond Fission Steps In Alkene Losses From Oxonium Ions Via Routes That Are Formally Isoelectronic With The Retro 'ene' Pericyclic Process Are Emphasized.
