Selenides, alkenyl phenyl synthesis

Alternatively, 1-lithio-l-alkenyl phenyl and methyl selenides have been obtained on reduction of the C—Se bond of l,l-di(seleno)alkenes with alkyllithiums this reaction is the only one which allows the synthesis of the methylseleno derivatives (Scheme 41). ... 

The coupling of arylzinc halides with alkyl (E)-2,3-dibromoalkenoates occurs at C-3. 3-Arylindoles are obtained from 3-indolylzinc halides with haloarenes." A synthesis of 1,4-disubstituted butadienes starts from the hydrozirconation of ethynyl phenyl selenide. After Pd(0)-catalyzed coupling with alkenyl bromides, the seleno group is replaced via Grignard reaction in the presence of (Ph3P)2NiCl2.
