The Grignard reagent functions as an allyl anion equivalent in the reaction with thioacetals catalyzed by Dichlorobis(triphenyl­phosphine)­nickel(II)­, 13930: J. Am. Chem. Soc., 111, 9119 (1989):

The lithio-derivative reacts with Bis(cyclopentadienyl)­titanium dichloride, A11456, to give bis(cyclopropyl)titanocene, which reacts with carbonyl compounds to give alkylidenecyclopropane derivatives: Tetrahedron Lett., 34, 943 (1993). Similarly, esters and lactones give enol ethers and acetylenes give vinylcyclopropanes.
