Nucleophilic Aromatic Substitution Reactions of Borabenzene-Trimethylphosphine:  A Versatile Route to 1-Substituted Boratabenzenes

1,2-Azaborolyls, Isoelectronic Analogues of the Ubiquitous Cyclopentadienyl Ligand: Synthesis of B-Heteroatom-Substituted 1,2-Azaborolyl Complexes and an Assessment of Their Electronic Features

“…1,2‐Azaborolyls are isoelectronic with cyclopentadienyls (Scheme ). As with boratabenzenes,9 the boron of azaborolyls provides a potentially straightforward point of attachment for substituents that can modulate the electronic nature of the boron heterocycle 10…”

Silyl stabilized azanes: Reactions of mono- and dilithium bis(trimethylsilyl)hydrazide with dichloro- and tetrachlorostannane

“…Current research continues to uncover fascinating new ring systems which pose intriguing questions with respect to their bonding or which exhibit unexpected reactivity. Some noteworthy examples include 6p-electron gallium-based systems and pseudo aromatic cyclic silylenes [1,2], novel cyclic tellurium imides [3] and interesting aluminum-nitrogen heterocycles [4] among others [5][6][7][8]. In addition to the studies on bonding and reactivity, a further reason for studying inorganic rings is their potential use as precursors to polymers and solid-state materials.…”

Anionic Phosphane − A New Ligand with a Phosphane and a Weakly Coordinating Heteroborate Moiety

“…[7] Substitution reactions at the boron atom of borabenzeneϪtrimethylphosphane with K[PPh 2 ] resulted to give the phosphide K[C 5 H 5 BPPh 2 ] in excellent yield. [8] Syntheses of monoboranephosphides [R 2 PBH 3 ] Ϫ and examples for their coordination at Li, Al, Fe, Pd, and Pt can also be found in the literature.…”
