phenacylide [ → py+C̄(COPh)C5F4N-4] and a range of pyridinium alkoxycarbonylmethylides [ → py+C̄(CO2R)C5F4N-4, R = Me, Et, Prn, Pri, CH2CCl3, CH2CF3, CH2Ph, CH2CH2Ph]. A detailed analysis of the mass spectrometric fragmentation patterns for the alkoxycarbonyl compounds has been carried out. Spectroscopic data has also been obtained for pyridinium methylides synthesised from pyridinium ethoxycarbonylmethylide
九个新的吡啶鎓methylides已经通过S合成Ñ从五氟4-氟吡啶鎓phenacylide的氩位移[→PY + C̄(COPH)C 5 ˚F 4 N-4]和一系列吡啶鎓alkoxycarbonylmethylides的[→PY + C̄(CO 2 R)C 5 F 4 N-4,R = Me,Et,Pr n,Pr i,CH 2 CCl 3,CH 2 CF 3,CH 2 Ph,CH 2 CH 2Ph]。已经对烷氧基羰基化合物的质谱碎裂模式进行了详细分析。还获得了由吡啶鎓乙氧基羰基甲基化物和3-氯四氟吡啶或八氟甲苯合成的吡啶鎓甲基化物的光谱数据。
