The 12-ethynylmonocarba-closo-dodecaborate anion as a versatile ligand for Cu(i) alkyne and heterobimetallic Cu(i)/M(ii) (M = Pd, Pt) alkynide complexes


Jiang, Tao; Zhang, Kang; Shen, Yunjun; Hamdaoui, Mustapha; Dontha, Rakesh; Liu, Jiyong; Spingler, Bernhard; Duttwyler, Simon (2019). The 12-ethynylmonocarba-closo-dodecaborate anion as a versatile ligand for Cu(i) alkyne and heterobimetallic Cu(i)/M(ii) (M = Pd, Pt) alkynide complexes. Dalton Transactions, 48(46):17192-17199.

Abstract

The anionic monocarborane alkyne [12-(HC[triple bond, length as m-dash]C)-CB11H11]− was employed as a ligand towards Cu(I) to form terminal alkyne complexes. Spectroscopic methods and X-ray crystallography allowed for a detailed structural analysis of complexes with nitrogen ligands, which are the first examples featuring carborane-C[triple bond, length as m-dash]CH → metal π coordination. Addition of phosphines to compound 2 afforded homoleptic Cu(I) complexes [Cu(PR3)n]+ (4), in which case the carborane becomes a non-coordinating anion. Polymeric acetylide 5 was obtained in almost quantitative yield from 2 and proved to be a suitable precursor to heterobimetallic Cu(I)/M(II) (M = Pd, Pt) alkynide complexes with side-on and end-on coordination to the metal centers.
