Interpretation Introduction

Interpretation:

The structures of compounds A, B and C for the given reaction scheme should be drawn.

Concept Introduction:

Preparation of Grignard reagents: They are prepared by reaction of organohalide in presence Mg in ether solvent.

    R-XEt2OMgR-Mg-Xhere R-X=organohalide R-Mg-X=organomagnesiumhalide

Preparation of organozinc: They are prepared in the same way as preparation of Grignard reagents.

    R-XEt2OZnR-Zn-Xwhere R-X=organohalideR-Zn-X=organozinchalide 

Negishi coupling: It describes how the product obtained when organometallic compound containing Zn,AlandZr is coupled with organic electrophile in presence of palladium or nickel catalyst.

Stille coupling reaction: The reaction that involves coupling of an aryl, benzyl or vinyl halide or triflate with stannane in presence of Pd(PPh3)4.
