Abstract

Reaction of (PNP)Os(H)₃ (PNP = (^tBu₂PCH₂SiMe₂)₂N-) with N₂O forms (PNP)OsH(N₂) and H₂O in 1 h at 22 °C. The mechanism of this reaction is probed with DFT (B3LYP) calculations. (PNP)OsH(N₂) forms a 1:1 adduct with CO and with HCCH and is protonated (by triflic acid) to [PN(H)P]OsH(N₂)⁺, which only slowly transforms to (PNP)Os(H)₂(OTf) by liberation of N₂.
