    • 3N (0.33 mL, 2.3 mmol). The reaction mixture was stirred at ca 70°C for 10 min and cooled to 20°C, after which stirring was continued for 4-5 h. The precipitate that formed was filtered off and washed successively with 50% and 96% EtOH and hexane. After recrystallization from EtOH, cyclopropanes 7 and 9 were obtained (Table 1).

    • max = 25°). The structure was solved by direct method and refined by full-matrix least squares. Non-hydrogen atoms were refined anisotropically. All hydrogen atoms were placed to the calculated positions. The final R factors were R = 0.0457 (2230 independent reflections) and R = 0.1357 (2796 independent reflections). All calculations were performed using the SHELXL97 program. Details of X-ray analysis including atom coordinates and their isotropic equivalent temperature parameters will be given in a full report.
