Stepwise Bromination of Two Acetylene Molecules on a Butterfly-Type Tetrairon Core and Reactivity of the Resulting Bromoacetylene Fragment toward Nucleophiles

“…There have been limited examples of haloalkyne-coordinated complexes and clusters to date, probably due to the relative inaccessibility of haloalkynes, − and most complexes have been synthesized by reactions of transition metal complexes with haloalkynes. The reactivity of these complexes remains largely unknown.…”

Electric Multipole Moments and (Hyper)Polarizability of X–C≡C–X, X = F, Cl, Br and I

“…Dichloroethyne is a very toxic molecule [5] and its determination in environmental atmospheres containing halogenated hydrocarbons is an important problem [6]. The structure and chemical bonding of dichloroethyne, dibromoethyne and diiodoethyne complexes has attracted some attention [7][8][9]. Although in the past decade numerous experimental and spectroscopic studies have focused on the determination of the structure and spectroscopic properties of dihaloethynes [10][11][12][13][14][15][16][17][18][19][20], very little is known about their electric properties.…”
