GAS-PHASE REACTIONS .61. NITRILE IMINES RC=+N--N-SI(CH3)3 - OPTIMIZATION OF GAS-PHASE SYNTHESIS AND ASSIGNMENT OF THEIR PHOTOELECTRON-SPECTRA
The flash vacuum pyrolysis of 5-R-2-trimethylsilyl-tetrazoles to nitrile imines RC N ⊕ N {circled dash}Si(CH) with R = CH, CH has been optimized by real-time photoelectron spectroscopic gas analysis and the assignment of their ionization patterns confirms the proposed frontier orbital sequence, which allows a rationalization of their regioselectivity in 1,3-dipolar additions
