Two atoms of this element flflank a carbonyl group in phosgene,and it is present in both compounds that make up Lucas's reagent.
It's not sulfur, but in a poorly-understood mechanism, this element strongly poisons low temperature shiftft catalysts. In acommon industrial process, this element continually oxidizes ammonia and amino acids, until the breakpoint is reached, pastwhich its residual is freely available. One atom of this element appears in a protecting group which is removed by piperidinein a manner that does not disrupt the peptide-resin linker, in solid-phase peptide synthesis. Carbon-13NMR uses a deuteratedcompound primarily consisting of this element as a solvent. Two atoms of this element flflank a carbonyl group in phosgene,and it is present in both compounds that make up Lucas's reagent. Among elements of its group, it has the second-highestreactivity in a free-radical transformation in which it is added to alkanes. The most commonly-used "thionyl" compound replacesalcohols with this element, four atoms of which are present in a noted tetrahedral compound abbreviated "carbon tet."For 10 points, name this halogen, which along with flfluorine is present in CFCs.
