High resolution microwave spectra for the somewhat unstable compound 1-chloroborepin were measured in the 5–10 GHz range using a pulsed beam Fourier transform microwave spectrometer. Transitions were assigned and measured for three isotopologues, w

This article presents the background of the author's synthesis of phosphabenzene in 1971. It also expands to tell the story behind the syntheses of the heavier group 15 heterobenzenes: arsabenzene, stibabenzene, and bismabenzene, which were prepared

BN-naphthalene (2) and BN-tetralin (7) have been prepared by a short synthesis from allyltributylstannane (3). The reaction of 3 with BCl3 followed by diallylamine and Et3N afforded (diallylamino)diallylborane (5), which gave 1,4,5,8-tetrahydro[1,2]a

The microwave spectra for seven unique isotopologues of 4a,8a-azaboranaphthalene [hereafter referred to as BN-naphthalene] were measured using a pulsed-beam Fourier transform microwave spectrometer. Spectra were obtained for the normal isotopologues

This review describes the syntheses and coordination chemistry of selected unsaturated borataheterocycles. These compounds are formally derived from common heteroaromatic rings by the isoelectronic substitution of an anionic BH− group for a neutral

Lithium 2-vinyl-1,2-azaboratabenzene 1b has been prepared by a multistep synthesis from 2,2-dibutyl-2,5-dihydro-1-trimethylsilyl-1 H -1,2-azastannole 6 . The reaction of 1b with one equivalent of [Cp ∗ RuCl] 4 gave the very labile sandwich compound

1,2-Dihydro-2-phenyl-1,2-benzazaborine reacts with Cr(CO)3(CH3CN)3 in THF at 140 °C to form complex 18, in which the phenyl is η6-bound to chromium. 1,2-Dihydro-2-methyl-1,2-benzazaborine reacts with Cr(CO)3(CH3CN)3 in THF at 60 °C to form complex

1,2-Dihydro-2-phenyl-1,2-azaborine (5) reacts with Cr(CO)3(CH3CN)3 in THF at 50 °C to form the Cr(CO)3 complex 7 in which the chromium is η6-bound to the heterocyclic ring. Heating 7 in THF to 101 °C causes it to isomerize to complex 8, in which t

3a,7a-Azaborindene (14) has been prepared by two multistep syntheses using the Grubbs ring-closing metathesis from appropriate B-vinyl,N-allyl-aminoboranes. 14 was deprotonated by KN(SiMe3)2 to give 3a,7a-azaborindenylpotassium (5). The reaction of 5
