butyl, phenyl, and ethyl groups are displaced from tributylborane, triphenylborane, and triethylalane. Methoxy- and ethoxy-groups are displaced from trimethoxyborane, diphenylmethoxyborane, and some carboxylic esters; and acetate can also be replaced. Phosphinostannanes undergo similar reactions, as demonstrated by the exchange of diphenylphosphino- and butylthio-ligands.

Metathetical exchange reactions between (a) ethylaluminium chlorides or aluminiumchloride and (b) various silanes or trimethyltin chloride proceed under quite mild conditions. The Al–Et bond is cleaved more readily than the Al–Cl bond [e.g., 2Me3SiBr +(EtAlCl2)2→ 2Me3SiEt + Al2Br2Cl4].

Diastereotopic nonequivalence is described for molecules of the type R′Me2-SnCHY(CH3) (with YC2H5, C6H5 and with various R′ groups), for meso-R″2 Sn(CHYCH3)2 (with R″CH3, CH2C6H5) and for diastereoisomers such as Me4-n- Sn(CHZCH3)n [ZEt, Pr; n2,3] and Me-i-Pr-cyclo-HexSnCH(CH3) (C6H5).
非对映异构非对等是该类型R'Me的分子描述2 -SnCHY(CH 3)(与YC 2 ħ 5,C 6 H ^ 5并与各R'基团),对于内消旋-R“ 2 SN(CHYCH 3)2(具有R” = CH 3,CH 2 C 6 H 5),对于非对映异构体,例如Me 4- n - Sn(CHZCH 3)n [Z = Et,Pr; Ñ 2,3]和Me-I-PR-环HexSnCH(CH 3)(C 6 H ^ 5)。
