The First Structurally Characterized Aluminum Compound with Two SH Groups:  [LAl(SH)₂] (L = N(Ar)C(Me)CHC(Me)N(Ar), Ar = 2,6-i-Pr₂C₆H₃) and the Catalytic Properties of the Sulfur P(NMe₂)₃ System

Abstract

Surprisingly stable is the bis(hydrogen sulfide) of aluminum LAl(SH)(2) with two terminal arranged SH groups. The insertion of sulfur into the Al-H bonds is catalyzed by SP(NMe(2))(3). A possible mechanism is discussed.

[LAl(μ‐S3)2AlL]: A Homobimetallic Derivative of the Sulfur Crown S8

“…The SÀS bond length (av 2.08 ) in 2 is [8] and in [LAl(SH) 2 ] (av 2.22 ). [11] The AlÀN bond length (av 1.89 ) falls within the range of those in aluminum derivatives bearing the L ligand.…”

“…The β-diketimino group, in particular, has been a key ligand to a rich chemistry of respective aluminium dihydrides. [9][10][11][12] A prominent example is II (Fig. 1), which can The guanidinate IV, the phosphinimide V, as well as the troponimide VI (Dipp = 2,6-diisopropylphenyl).…”

“…9,10 In a different field of applied science one finds chemical vapour deposition technology exploiting the thermodynamic properties of molecular aluminium hydrides for the purpose of creating composite materials. 1,[13][14][15] Aluminium hydrides are considered as fuel storagematerials with reasonable prospects in a hydrogen-based alternate energy-supply concept.…”

Preparation of [LAl(μ‐S)2MCp2] (M=Ti, Zr) from the Structurally Characterized Lithium Complexes [{LAl(SH)[SLi(thf)2]}2] and [{LAl[(SLi)2(thf)3]}2]⋅2 THF

“…The recovery of the crystals was performed within 15 min of the addition of the solvent to avoid decomposition caused by free HN(SiMe 3 ) 2 . However, compound 2 loses THF upon drying in vacuo, leading to a dimeric product [{LAl[(SLi) 2 (thf) 2 ]} 2 ] (2') containing only four molecules of THF as determined by 1 H NMR spectroscopy. This final product proved to be stable upon storage for several months under an inert atmosphere.…”
