(10 mL) was added to this solution at -40°C. The reaction mixture was allowed to warm to ambient temperature, stirred for 30 min, and the products were purified by chromatography on silica using dichloromethane/pentane 1 : 1 as eluent. Compound 5 (60 mg, 3.8%) was isolated from the first fraction as yellow crystals. M.p. 85°C; IR (pentane) : 6 = 2028 (vs), 1942 (vs), 1919 (m) cm -' ; MS ( eV): mjz: 418 [ M ' 1, 362 [M' -2COl 216 [[CpMn(CO),(CNCH,)]+], 160 [[CpMn(CNCH,)]+], 120 [[CpMn]'], 55 [Mn+]. The second fraction gave 4 (180 mg, 19.6%) as yellow crystals. M.p. 76°C; 'HNMR (CD,CI,): 6 = 4.71 (C,H,, SH), 5.01 (CH,, 2H); "C {'H} NMR(CD,CI,): 6 = 50.1 (CH,), 83.4(C5H,), 162.01NC). 210.5 (NC), 228.1 (CO); IR (CH,CI,): 6 = 2147 (m), 2086(m), 2010(m), 1903 (vs) cm-'; MS(70 eV): m/z: 242 [M'].
