The Interaction of Complexes of Composition MnLX2 (L=Tertiary Phosphine) with Dioxygen
TL;DR: In this article, the authors have shown that all of the complexes studied in this paper exhibit an irreversible decay channel in the presence of dioxygen to a phosphine oxide complex decomposition product at ambient temperature.

Abstract: : The complexes MnBr2PMe3, MnBr2PEt3, and MnBrPPhMe2 have been prepared as films on infrared windows under completely anhydrous conditions with care being taken to eliminate all free phosphine. These films have been exposed to dioxygenation/evacuation cycles in a specially designed infrared cell with infrared spectra being monitored under carefully controlled conditions. This work has indicated that such complexes do exist in solid-state films and do interact with dioxygen. However, the extent of the reversibility of the interaction with dioxygen is markedly dependent upon the nature of the tertiary phosphine ligand employed. All of the solid-state complexes studied in this work exhibit an irreversible decay channel in the presence of dioxygen to a phosphine oxide complex decomposition product at ambient temperature.

INTERACTION OF MnLX2 COMPLEXES WITH SULFUR DIOXIDE
TL;DR: In this paper, a series of MnLX2/SO2 adducts were obtained which were reversible in that the SO2 could be removed upon evacuation, however, a competitive decomposition channel existed, which was accentuated by longer exposures and higher pressure.
