Unless otherwise stated, all starting materials and catalysts were purchased from commercial sources and used without further purification. All solvents were distilled and degassed with nitrogen before use. Isocyanides 1a−1f, tetraphenyllead 2a, and hexaphenyldilead 2g were purchased from commercial supplies. Isocyanides 1g−1o were prepared according to the procedure that we previously reported.6 Tetraaryllead 2b−2f were prepared according to the procedure.14 1H NMR spectra were recorded on a JEOL JNMECS400 (400 MHz) FT NMR system or a JEOL JNM-ECX400 (400 MHz) FT NMR system in CDCl3 and C6D6 with Me4Si as an internal standard. 13C NMR spectra were recorded on a JEOL JNM-ECX400 (100 MHz) FT NMR or a JEOL JNM-ECS400 (100 MHz) FT NMR in CDCl3 and C6D6. 19F NMR spectra were recorded on a Variant NMR System 400 (376 MHz). IR spectra were reported in wave numbers (cm−1). ESI and EI mass spectra were obtained by employing double-focusing mass spectrometers. High-resolution mass spectra (HRMS) were obtained on a JEOL JMS-AX500 or MALDI TOFMS and were obtained on an Applied Biosystems 4800 MALDI TOF/TOF analyzer.
