Abstract

Green, crystalline Cp₃UCHPMe₃ has been synthesized by the reaction of Cp₃UCl with Li[CH₂]₂PMe₂ or CH₂PMe₃. Its crystal structure has been determined by single crystal X‐ray diffraction. The short UCH bond distance, 2.274(8) Å, and large UCP angle, 143.5(5)°, indicate uranium‐carbon multiple bond character. The ¹J(¹³C¹H) coupling constants within the CH group between uranium and phosphorus in Cp₃UCHPPh₂Me (95 Hz), Cp₃UCHPMe₂Ph (100 Hz), and Cp₃UCHPPh₂Me (113 Hz) are surprisingly small, but no agostic interaction UCHP can be derived from the structural data.
