一系列选择性含有2-噻吩基,3-噻吩基,5-甲基-2-噻吩基,5-叔丁基-2-噻吩基,4-甲基-2-噻吩基和3-的四有机锡(IV)化合物的合成据报道,式R 4- n Sn [L] n(R = Ph,对甲苯基,Me,环戊基,环己基; n = 1-4)的(2-吡啶基)-2-噻吩基[L] 。考虑了从119m SnMössbauer和NMR(13 C和119 Sn模式)光谱得出的结构感兴趣的特征。
Organocopper compounds add to enones and enoates in the presence of chlorotrimethylsilane in ether giving the conjugate adducts in preparatively useful yields via the silyl enol ethers. Presence of lithium iodide is important and excess of chlorotrimethylsilane accelerates the reactions.
