โœฆ Synopsis

The successful isolation of NiL(CO13 and NiLa-(CO) (L = Me@PFJ is reported. Boron tn'fluoride reacts with NiL2(CO)2 to yield NiL,(CO)2*nBF3, where n = 1.44 at -128 'Cand I.11 at 2 "C, and with NiL4 to yield NiL.,*nBF,, where n = 2.6 at -100 "C, n = 1.78 at -3 "C and n = 1.24 at +20 "C. Nuclear magnetic resonance and infrared spectral data is presented which indicates that the BF, coordinates to the nitrogen of the coordinated MezNPFz ligands.

Mass spectral data for the adducts has also been obtained.

N-Haloelectrophiles react with alkenes in the presence of boron trifluoride etherate to give halofluorides and N-halo adducts. There is a diverse group of positive halogen compounds containing the nitrogen-halogen bond. The group includes N-haloamines, N-haloamides, and N-haloimides. Although radic
