This review describes the syntheses and coordination chemistry of selected unsaturated borataheterocycles. These compounds are formally derived from common heteroaromatic rings by isoelectronic substitution an anionic BH− group for a neutral CH group. Specifically included five-membered 1,2- 1,3-thiaborolyls, thiophene, 1,2-oxaborolyl, furan, 1,2-azaborolyl, pyrrole. Also is six-membered ring 1,2-azaboratabenzene, pyridine. can serve as surrogates cyclopentadienyl in organometallic compounds.

The reaction of 2 equiv lithium 1-phenylboratabenzene with ZrCl4 in ether affords bis(1-phenylboratabenzene)zirconium dichloride (2), while [4-tert-C4H9C5H4BPh]2ZrCl2 (3), obtained a similar manner, was subjected to single-crystal X-ray diffraction study. solution and methylaluminoxane (MAO) C2H4 (1 atm, 25 °C) ethylene oligomers (dimers 1-alkenes as the major product, together minor amounts 1- 2-alkenes).
1,2-Dihydro-1,2-azaborines (1c, 1d, and 1e) have been prepared by the reaction of corresponding 2,3-dihydro-1H-1,2-azaborol-3-yllithium reagents 1e). The 1e with Py3Mo(CO)3 BF3·OEt2 affords Mo(CO)3 complex 5e, while 1c Cr(CH3CN)3(CO)3 Cr(CO)3 6c. X-ray structures 5e 6c show that metals are η6-bound to 1,2-dihydro-1,2-azaborine rings.
The aromatic boron-nitrogen heterocycle 1,2-dihydro-1,2-azaborine undergoes classical electrophilic substitution. These reactions allow easy functionalization to provide a variety of 3- and 5-substituted derivatives. [reaction: see text].
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 KN(SiMe3)2 to give 3a,7a-azaborindenylpotassium (5). The reaction of 5 with Cp*ZrCl3 afforded corresponding Zr(IV) complex 18, which on activation excess methylaluminoxane, forms a good catalyst for polymerization ethylene. methylene chloride and BuLi gave 4a,8a-azaboranaphthalene (6), is isoelectronic isostructural...
