The novel boron persulfide 2 LB(η(2) -S2 ) (L=[ArNC(R)CHC(R)](-) ; Ar=2,6-Me2 C6 H3 , R=tBu) was obtained by the reaction of the 2-chloro-azaborolyl anion 1 (LBCl)K(THF) with 0.25 equiv of elemental sulfur (S8 ). Persulfide 2 is labile in solution and could be converted to the cyclic tetrasulfide LBS4 (3) and hexasulfide LBS6 (4) in the presence of sulfur at room temperature and 50 °C, respectively. Desulfination of 2 with triphenylphosphine resulted in the formation of the thioxoborane LB=S (5… Expand

Reactivity of the 2‐Chloroazaborolyl Anion
The reactivity of 2-chloro-azaborolyl anion (LBCl)[K(THF)] (1, L = [ArNC(R)CHC(R)]-; Ar = 2,6-Me2C6H3, R = t-Bu) was investigated. Treatment of 1 with a diazomethane resulted in the formation of aExpand
A BH Borenium-Derived Thioxoborane, Its Persulfide, and Their Li+-Induced Reactions with Alkynes and with Carbon Dioxide.
TLDR
The boron persulfide formally inserted phenyl acetylene into the B-S bond in the presence of Li[B(C6F5)4] to give the respective five-membered heterocycle. Expand

Advances in the development of complexes that contain a group 13 element chalcogen multiple bond.
TLDR
The literature on complex compounds that exhibit a bonding interaction between a group 13 element atom and a chalcogen atom that is reasonably to be interpreted in terms of a double- or triple bond is revised. Expand

TLDR
The synthesis of heterobimetallic cluster with the Al-S-M (M = Cu and Ag) structural unit has been realized for the first time by the reaction of aluminum-dithiol LAl(SH)2 with excess of sulfur and (MesAg)4, which resulted in the formation of LAlS4 as the only product soluble in organic solvents.
