Reactions of thiols RSH (R = Et, i Pr, t Bu) with AlH 3 ·NMe 3 lead to RSAlH 2 ·NMe 3 or (RS) 2 AlH·NMe 3 compounds, depending on the stoichiometry. Similarly, the 1:1 reaction of LiAlH 4 with RSH (R = Et, i Pr) in ether produces LiAlH 3 SR, however, in the case of NaAlH 4 and i PrSH in THF, ligand exchange of NaAlH 3 (SR) to NaAlH 4 , NaAlH 2 (SR) 2 and NaAlH(SR) 3 occurs. A byproduct of the formation of LiAlH(S t Bu) 3 ( 6 ), in ether is [(Et 2 O)LiAlH(S t Bu) 3 ·LiS t Bu] 2 ( 7 ). Reaction of a 1:1 mixture of LiAlH 4 with AlH 3 ·NMe 3 and HS t Bu (1:1:5) leads to LiAlH(S t Bu) 3 ·AlH(S t Bu) 2 NMe 3 ( 8 ). Compounds 5 , 7 and 8 were characterized by X‐ray structure determinations. All molecules contain tetracoordinated Al centers.
