Diiodomethane-Zinc-Titanium isopropoxide

Diiodomethane-Zinc-Titanium(IV) isopropoxide, 115 Iodomethyltrimethylsilane, 315 Tributyl(iodomethyl)tin, 314 a-METHYLENE-y-BUTYROLACTONES (see Un-saturated Lactones)... [Pg.395]

It is possible to exclusively methylenate a ketone in the presence of an aldehyde by precomplexing the aldehyde (e.g. 76) with Ti(NEt2)4, followed by treatment with the usual methylene zinc/TiCU reagent (equation 17). Takai also studied the chemoselective methylenadon of aldehydes (78) in the presence of ketones, and found the use of diiodomethane, zinc and titanium isopropoxide or trimethylaluminum to be effective (equation 18). ... [Pg.750]
