10] The metallation of lithium morpholine to obtain the complex di(morpholine)titanium dichloride is similar to the metallation of indene and cyclopentadiene to obtain di(indenyl)titanium dichloride and di(cyclopentadienyl)titanium dichloride respectively and they were subsequently developed to enviable demand complexes.
