摘要

Reactions of laser-ablated Pt atoms with CH4 during condensation in excess argon form CH3-PtH through oxidative C-H insertion show and that the late transition-metal atom Pt is an effective methane activation reagent,in agreement with gas phase investigations.Six observed infrared absorptions correlate with the six strongest calculated harmonic frequencies.The computed C-Pt bond length is slightly shorter than those of Pt complexes with large ligands.In addition,the strongest absorption of the CH2=PtH2 methylidene is detected.
