As long as a titanacyclopropane can be formed, other alkyl Grignard reagents can be used instead of ethylmagnesium bromide. For example, when alkylmagnesium bromide [R1(CH2)2MgBr] is used as a Grignard reagent, the substituted titanacyclopropane 31 is formed in situ. In the cyclopropanol formation, the R1 group is incorporated into the product 32 as a substituent at C2 after hydrolysis of the reaction mixture (Scheme 21).[‌92‌,‌98‌,‌99‌]
