Sulfur bridges : The reactions of [LAl(SH) 2 ] (L=HC(CMeNAr) 2 , Ar=2,6‐ i Pr 2 C 6 H 3 ) with LiN(SiMe 3 ) 2 in molar ratio 1:2 and 1:1, respectively, lead to species with the formula [{LAl[(SLi) 2 (thf) 3 ]} 2 ]⋅2 THF and [{LAl(SH)[SLi(thf) 2 ]} 2 ] in high yields. These lithium salts react further with [Cp 2 MCl 2 ] (M=Ti, Zr; Cp=C 5 H 5 ) to give unique heterobimetallic sulfides of composition [LAl(μ‐S) 2 MCp 2 ] (see structure; M=Ti).
