摘要: Abstract Substituent effects on 199 Hg 1 H and 13 C spinspin coupling constants have been studied for neopentylmercury derivatives, (CH 3 ) CCH 2 HgR(or X), where R is covalently bonded Me, Et, t-Bu, neopentyl, vinyl, X easily ionizable CN, Br, Cl, OCOCH , ONO . Linear relationships exist between the methylene J ( CH) (HgH), 4 (HgC) (HgC); but deviations from linearity occur chloride, bromide, acetate, nitrate in (HgH) (HGH) (HGC). These are discussed terms of hyperconjugative p π d bonding CH bonds mercury.
