want not: A mechanistic study of the ruthenium‐catalyzed haloalkylation of titanium enolates led to the development of a process that is catalytic in both metals: titanium and ruthenium (see scheme; Bn=benzyl, PMP=1,2,2,6,6‐pentamethylpiperidine). Catalytic turnover was observed in the formation of the titanium enolates from N‐acyl oxazolidinones, and insight was gained into the inhibitory effect of the
