J . A m . Chem. SOC.1986, 108, 4867-4873 UV Irradiation of Cp(PMe3)Re(q2-CH2PMe2)H(10) with P(CD&3. A solution of 10 (2 mg, 0.005 mmol,0.01 M) and P(CD3)3(0.005 mmol,
0.01 M) in 0.41 mL of cyclohexane-d12was prepared in a sealed NMR tube. 31P('H]NMR analysis revealed the ratio 10/P(CD3), = 1.4. Irradiation for 1 h followed by 'HNMR analysis showed that no reaction had occurred (
