The syntheses and first structural characterization of terminal (diisopropylamino)borylene complexes are reported. The ^{11}B NMR chemical shifts for these novel systems (δ _{B} 93.8 and 90.2 for [Cp'Fe(CO)_{2}(BN^{i}Pr_{2})][BAr^{f}_{4}], 3, and [CpRu(CO)_{2}(BN^{i}Pr_{2})][BAr^{f}_{4}], 4, respectively) are ca. 40 ppm downfield of those measured for the boryl precursor complexes, consistent with observations for related trimethylsilyl and cyclohexylamino substituted compounds. Structurally, the linearity of the M – B – N fragment in each case and the marked shortening of the M – B bonds (cf. the single bonds found in boryl complexes CpFe(CO)_{2}(BN^{i}Pr_{2})Cl, 1b, and CpRu(CO)_{2}(BN^{i}Pr_{2})Cl, 2) reflect the fact that the M – B bond order in borylene systems 3 and 4 is between one and two. |
