Several modifications of the alkene synthesis employing the Shapiro protocol with subsequent trapping of the intermediate alkenyl anion 196 with electrophilic alkylating agents such as alkyl halides or alkyl sulfates have been developed (Scheme 66).[‌389‌‌391‌] Examples of this procedure for the synthesis of substituted alkenes, e.g. 197 are shown in Table 48.[‌355‌,‌380‌,‌383‌,‌389‌‌393‌]
