These reactions usually proceed more slowly than the reactions of the corresponding alcohols or phenols with boron halides. In some cases, where direct reaction is too slow, the lead or mercury derivatives of thiols are used. Attempts to use the reactions of thiols with diboron trisulfide to prepare trialkylthioboranes have usually been unsuccessful, although analogous reactions with oxygen compounds are commonly used to prepare trialkoxyboranes.

Other reported binary boron sulfides include subvalent B12S, a black crystalline material prepared by a high-temperature reaction of amorphous boron with elemental sulfur, and BS, which has been studied spectroscopically in an electric discharge. A vapor-phase dimer, (BS)2, was identified, and a refractory condensed form of BS was reported from the reaction of elemental boron with sulfur at 1850 °C and a pressure of 94 500 atmospheres. Boron disulfide, BS2, has been identified in the gas phase and appears to be the primary compound present in the vapor phase over diboron trisulfide or elemental boron and sulfur. 

ACETATO MERCURIOSO (Spanish) (21908-53-2) A strong oxidizer. Violent reaction with reducing agents, acetyl nitrate, diboron tetrafluoride, disulfur dichloride, combustible materials, fuels, hydrazine hydrate, hydrogen peroxide, hydrogen trisulfide, hypophospho-rous acid, methanethiol, phospham. sodium-potassium alloy, sulfur, sulfur trioxide. Incompatible with alcohols, alkali metals, ammonium nitrate, diboron tetrafluoride, hydrazinium nitrate, hydrogen sulfide, nitroalkanes, rubidium acetylide, selenium oxychloride. Forms heat-, friction-, or shock-sensitive explosives with anilinium perchlorate, chlorine, phosphorus,. sulfur, magnesium, potassium, sodium-potassium alloy.
