실험 절차
A solution of 257 mg (1.02 mmol) N,N-diallyl 4-methylbenzenesulfonamide (prepared according to S. Varray, R. Lazaro., J. Matinez, F. Lamaty, Organometallics 2003, 22, 2426-2435) and 19 mg (0.03 mmol) [RuCl2(ImH2Mes)((4-chloro-2-trifluoromethyl-8-quinolinyl)methylene)] in 5 ml toluene was stirred at 110° C. To monitor the conversion and selectivity, 0.2-ml samples were taken were after 1 h and 4 h. Each sample was filtered over a silica gel pad, the filtrate was evaporated to dryness and analyzed by GC (column: DB-1701; injector: 260° C.; detector: 260°; oven: 70 to 250° C./5° C. per min; carrier gas: H2 (60 kPa); retention times: 15.5 min N,N-diallyl 4-methylbenzenesulfonamide, 24.5 min 1-(toluene-4-sulfonyl)-2,3-dihydro-1H-pyrrole, 25.5 min 1-(toluene-4-sulfonyl)-2,5-dihydro-1H-pyrrole). After 1 h (98% conversion), 96% of the title compound and 2% of 1-(toluene-4-sulfonyl)-2,3-dihydro-1H-pyrrole and after 4 h (100% conversion) 92% of the title compound and 8% of 1-(toluene-4-sulfonyl)-2,3-dihydro-1H-pyrrole were formed. 1H-NMR of 1-(toluene-4-sulfonyl)-2,5-dihydro-1H-pyrrole (300 MHz, C6D6): 2.43 (s, 3H); 4.12 (s, 4H); 5.65 (s, 2H); 7.32 (d, J=8.3 Hz, 2H); 7.73 (d, J=8.3 Hz, 2H). 1H-NMR of 1-(toluene-4-sulfonyl)-2,3-dihydro-1H-pyrrole (300 MHz, C6D6): 2.40-2.55 (m, 2H); 2.43 (s, 3H); 3.48 (t, J=8.9 Hz, 2H); 5.10-5.15 (m, 1H); 8.35-8.40 (m, 1H); 7.32 (d, J=8.3 Hz, 2H); 7.67 (d, J=8.3 Hz, 2H).
