A carbon atom is bound to this element with a positive charge in a (*) betaine that is formed by the reaction of a ylide with this element attached to three phenyl groups.
This element is surrounded by cyclohexyl groups in a ligand which interacts with ruthenium and gets replaced by a chelating isopropoxy ligand during the action of a Hoveyda catalyst in olefin metathesis. Four atoms of this element each double bond to one oxygen and are bridged by an additional six oxygen atoms in its most important oxide. A carbon atom is bound to this element with a positive charge in a (*) betaine that is formed by the reaction of a ylide with this element attached to three phenyl groups. This element appears in a salt used in the Wittig reaction. This element, which exists in red and white allotropes, exists as a 3- anion bound to four oxygens. For 10 points, name this glowing nonmetal found below nitrogen.
