C-H/C-C functionalizations with oxymethylated bicyclopropylidenes were accomplished with an iron catalyst under external oxidant-free conditions. The combination of the unique reactivity of bicyclopropylidenes with a robust iron(II) catalyst enabled C-C c

Deprotonation of bicyclopropylidene (1) and 7-cyclopropylidenedispiro[2.2.2.1]heptane (2) with butyllithium in tetrahydrofuran affords lithiobicyclopropylidenes, which react with electrophilic reagents to give the correspondingly substituted bicyclopropylidenes 3, 4 in high yields. No selectivity was observed in deprotonation of unsymmetrically spiroanellated bicyclopropylidenes such as 1-cyclopropylidenespiropentane (5) and 1-cyclopropylidenedispiro-[2.0.2.1]heptane (6).
