Article abstract of DOI:10.1016/0040-4039(84)80102-1

A short and efficient synthesis of bis(1-methylcyclopropyl)ketone (6) via the spiro-acetal 4 from α-methyl-γ-butyrolactone (1) has been found, and reductive dimerization of 6 by McMurry coupling yields tetrakis(1-methylcyclopropyl)ethylene (7) in competition with ring-opened products (8 and 9).
