Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The conversions of the dimeric imidazolin‐2‐iminato aluminum dihydride {μ‐L^DippAlH₂}₂ (<bold>1</bold>) with ¹/₄ or ¹/₂ equivalents of S₈ gave the elusive hydrogensulfide {μ‐L^DippAl(H)SH}₂ (<bold>2</bold>) and the bisthiol {μ‐L^DippAl(SH)₂}₂ (<bold>3</bold>), respectively (L^Dipp=NC(N(Dipp)CH)₂, Dipp=2, 6‐diisopropylphenyl). Notably, these transformations proceeded in the absence of a promoter. The reaction of {μ‐L^MesAlH₂}₂ (<bold>4</bold>), a less bulky congener of <bold>1</bold>, with phenyl disulfide produces the phenyl sulfide {μ‐L^MesAl(H)SPh}₂ (<bold>5</bold>; L^Mes=NC(N(Mes)CH)₂, Mes=2, 4, 6‐trimethylphenyl). The hitherto unknown compounds <bold>2</bold>–<bold>5</bold> were characterized by using spectroscopic methods and single‐crystal X‐ray diffraction analysis.</p> </abstract>
