Diphenylphosphinothioyl compounds were ortho-lithiated and alkyldiphenyl phosphine sulfides were α-lithiated and the resulting lithio compounds reacted to give the corresponding - and α-substituted products.

Reactions of benzyl diphenylphosphinothiite with a number of electrophiles have been investigated. It has been proved that a kinetically controlled process affords the S-attacked product, which is further converted into the transalkylated product, whereas a thermodynamically controlled process results in the formation of a P-attacked product. An intramolecular S → P migration of the benzyl group is suggested for the reactions with reactive electrophiles.
研究了二苯基硫代磷酸苄酯与多种亲电体的反应。研究证明,在动力学控制的过程中会产生 S 攻击产物,并进一步转化为反烷基化产物,而在热力学控制的过程中则会形成 P 攻击产物。在与反应性亲电体发生反应时,苄基会发生分子内 S → P 迁移。

Carbenes are highly enabling reactive intermediates that facilitate a diverse range of otherwise inaccessible chemistry, including small-ringformation and insertion into strong σ bonds. To access such valuable reactivity, reagents with high entropic or enthalpic driving forces are often used, including explosive (diazo) or unstable ( gem -dihalo) compounds. Here, we report that common aldehydes are
