consisting of aluminumtris(2,6-diphenylphenoxide) (ATPH) and MeLi has allowed the electrophilically activated nucleophilic ("amphiphilic") cleavage of C(alpha)-C(beta) bonds in gamma-stannyl ketones. Through combination with the conjugate addition of alpha-stannyl carbanion to enone, this approach constitutes a novel two-step conjugate addition - cleavage sequence that leads to functionalized ketones (see

Charge-transfer interactions of Ph3SnCH2SC6H4X-p (X MeO, Me, H, Cl or Br) with tetracyanoethylene are reported. Values of λmax, the absorption maxima, have been obtained and compared with the values for CH3SC6H4X-p(CN)2CC(CN)2 interactions. The effect of the Ph3Sn substituent is to shift λmax by 15–26 nm to longer wavelengths.
据报道Ph 3 SnCH 2 SC 6 H 4 X- p(XX MeO,Me,H,Cl或Br)与四氰基乙烯的电荷转移相互作用。λ的值最大,最大吸收,已经获得,并与为CH的值3 SC 6 H ^ 4 X- p (CN)2 CC(CN)2间的相互作用。在pH的影响3 Sn的取代基是至λ移位最大值由15-26纳米到更长的波长。
