Reactions of permanganyl chloride with allene in low-temperature matrices
摘要:
The light-induced (546 nm) reaction of MnO3Cl With allene has been investigated in low-temperature argon matrices at I I K. IR spectroscopic studies in combination with isotopic enrichment experiments (O-18, D) and DFT calculations (B3LYP/LanL2DZ) allowed the identification of (O=)(2)MnCl(O=CCH2CH2) (1), and (O=)(2)MnCl(H2COCCH2) (2) as the products. Possible ways for their formation are first of all discussed qualitatively in the context of the literature available, and then quantitatively with the background of DFT data (B3LYP/6-311G(d)) obtained for starting materials, products, transition states and intermediates. The most reasonable interpretation involves two-state reactivity. (c) 2007 Elsevier B.V. All rights reserved.
