摘要：

Extensive labeling studies permit to unravel the mechanisms by which bare Fe+ activates C–H and C–C bonds of n‐heptyltrimethylsilane in the gas phase. While the neutral products C3H8, C5H12, Si(CH3)4, and Si(CH3)3C25 are due to an initial insertion of Fe+ into various C–C bonds of the n‐heptyl chain, followed by β‐hydrogen transfer and reductive elimination of the neutrals, molecular hydrogen and HSi(CH3)3 ar suggested to result from initial activation of specific C–H bonds. The formation of C2H4 is preceded by a skeletal rearrangement of the heptyl chain, rendering C‐1/C‐4 and C‐2/C‐3 equivalent; a metallacycle 10 is suggested as an intermediate.
