Boron trichloride is the inorganic compound with the formula BCl 3. This colorless gas is a reagent in organic synthesis . It is highly reactive towards water.
Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...
Trimethylborane was first described in 1862 by Edward Frankland, [6] who also mentioned its adduct with ammonia. [7] Due to its dangerous nature the compound was no longer studied until 1921, when Alfred Stock and Friedrich Zeidler took advantage of the reaction between boron trichloride gas and dimethylzinc. [8]
Boron trichloride gas is also an important chemical in semiconductor industry, however, not for doping but rather for plasma etching of metals and their oxides. [111] Triethylborane is also injected into vapor deposition reactors as a boron source. [ 112 ]

Boron trifluoride is the inorganic compound with the formula BF 3. This pungent, colourless, and toxic gas forms white fumes in moist air. It is a useful Lewis acid and a versatile building block for other boron compounds.
Massaging the belly in a clockwise motion can mimic the natural motility of the colon, which may help move feces or gas along, Mulvihill explains. The warm oil can also feel soothing.
