With bromine, sulfur forms only S2 Br2; the iodides of sulfur are unstable. Upon heating to 150°–200°C, the reversible reaction of sulfur with H2 begins, resulting in the production of hydrogen sulfide. Sulfur also forms compounds with hydrogen in which there is more than one atom of ...
bromine atoms as substituents and/or is alkyl substituted and/or is annellated to a benzene nucleus, or is aralkyl, alkoxy or the radical R7R8HC-, where R7 and R8 are H or phenyl, may be prepared by reacting, if desired in the presence of a base and/or inert solvent, an oxosulph...

SULFUR reacts violently with strong oxidizing agents causing fire and explosion hazards [Handling Chemicals Safely 1980 p. 871]. Reacts with iron to give pyrophoric compounds. Attacks copper, silver and mercury. Reacts with bromine trifluoride, even at 10°C [Mellor 2:113. 1946-47]. Ignites ...
i) The formation of a curdy white precipitate that issolublein NH4OH indicates the presence of chlorine in the organic compound. ii) The formation of apale yellowprecipitate that ispartially solublein NH4OH confirms the presence of bromine. ...
