Photostimulated substitution reactions of t-BuHgCl with PhCH=CHQ (Q = I, PhSO2, ClHg) proceed by a radical chain.With t-BuMgCl in THF, stereoselectivity excludes this process for Q = I but with Q = PhSO2 (dark or hν) or HgCl (hν), radical substitution occ

Radical chain processes occur in conjugate addition reactions of 2-cycloalkenones with t-BuHgl2(1-), (t-Bu)2CuLi or (t-Bu)3ZnLi as judged by the relative reactivity of 2-cyclopentenone > 2-cyclohexenone and by the effect of CH2=CPh2 as a radical trap.On t

Substitution for Q in the systems PhCH=CHQ, Ph2C=CHQ, and PhCCQ can occur by a free-radical chain mechanism where the attacking radical is alkyl (Q = HgX, Bu3Sn, PhSO2, PhSO, PhS, Cl, Br, I) or (EtO)2PO. (Q = HgX, Bu3Sn, I).The Q. radicals formed by β-elimination can generate t-Bu. or (EtO)2PO. by reaction with t-BuHgCl, Hg2, ClHg or by electron transfer between .HgCl and (EtO)2PO-.With Q = PhS or PhSO2, relative reactivity data indicates that the free radical addition-elimination sequence occurs for t-BuLi at 0 or 45 deg C andthat this process may also be involved in reactions of t-BuMgCl or tert-butyl cuprates with some of the substrates.Ionic reaction of (EtO)2PO- with the three substrates with Q = PhSO2 or halogen are examined.With Q = PhSO2, PhCHCH2P(O)(OEt)2, Ph2C=CHP(O)(OEt)2, and PhCCP(O)(OEt)2 are formed in good yield.
