Abstract
[Li{(2-NC5H4)2P}{thf}]2(thf = tetrahydrofuran) and [AlMe2{(2-NC5H4)2P}]3 are obtained in high yield by treating (2-NC5H4)2PH 1, with BunLi and Me3Al, respectively; the X-ray-structure determination confirms that 2 is the first contact ion pair of a lithium diorganophosphide without Li–P contact, which makes the (2-NC5H4)2P– ion a versatile ligand for III/V precursors (already established in 3).Keywords
