AbstractWe report a systematic density functional theory investigation for the reactions of LiCH2I, IZnCH2I, iodomethylzinc phenoxide (PhOZnCH2I), 2,4,6-F3-PhOZnCH2I, and 2,4,6-Cl3PhOZnCH2I with CH2CH2, trans-CH3CHCHCH3, and PhCHCH2. All of the reactions examined displayed similar concerted mechanisms for the cyclopropanation of these reagents. The zinc carbenoids had similar barriers for the cyclopropanation reaction (in the 17-21 kcal/mol range), while the LiCH2I carbenoid had a much lower barrier for the cyclopropanation reactions (in the 6-7 kcal/mol range). The properties and chemical reactivity of the carbenoids investigated here were compared to each other and to recent results for the isodiiodomethane (CH2I-I) species.
