Transmetallation of Pb(OAc)₄ with R₂Hg (1), followed by treatment with HCl in Et₂O, provided RPbCl₃ (2), the first kinetically stabilized monoorganolead trihalide that resists reductive elimination under ambient conditions. The kinetic stabilisation relies on an intramolecularly coordinating O‐donor substituent (R=6‐Ph₂P(O)‐Ace‐5‐). The gram‐scale preparation of 2 was key for the synthesis of unsymmetrically substituted diaryllead dichlorides RR′PbCl₂ (3 a, R′=Ph; 3 b, R′=4‐MeOC₆H₄; 3 c, R′=4‐Me₂NC₆H₄).

单芳基三氯化铅可抵抗还原性消除

用R ₂ Hg（1）对Pb（OAc）₄进行金属转移，然后在Et ₂ O中用HCl处理，得到RPbCl ₃（2），这是第一种在环境条件下抵抗还原消除的动力学稳定的单有机三卤化物。动力学稳定取决于分子内配位的O-供体取代基（R = 6-Ph ₂ P（O）-Ace-5-）。的克规模制备2是为不对称取代diaryllead二氯化物的合成关键RR'PbCl ₂（3，R'= Ph值;图3b，R'= 4-MeOC ₆ H ^ ₄; 3 c，R'= 4-Me ₂ NC ₆ H ₄）。
