β′-Chloro and β′,γ′-unsaturated trichlorotitanium enolates, which were formed in situ by titanium(IV) chloride-mediated ring cleavage of 3,3-dialkylcyclobutanones and 3-[(trimethylsilyl)methyl]cyclobutanones, reacted with enones to give Michael adducts wi
Facile activation of zinc. Preparation of cyclobutanones via dichloroketene and cyclopropanes using the Simmons-Smith reaction

Zinc powder activated by heating in an inert atmosphere gave good yields when used for the title reactions. The very easy work up procedure for the cyclobutanones further increases the potential of the method.
Selective synthesis of glutaric acids from olefins
Depres,Greene
, p. 7065 - 7068 (2007/10/02)
Six representative glutaric acids have been regio- and stereoselectively prepared from the corresponding olefins in 49 to 65% overall yields. α,α-Dichlorocyclopentanones, readily available from the olefins by three-carbon annelation, are transformed via chloro enol acetates to the glutaric acids.
