ch 3 (ch 2) 7 ch=ch(ch 2) 11 co 2 h + o 3 + 0.5 o 2 → ch 3 (ch 2) 7 co 2 h + ho 2 c(ch 2) 11 co 2 h A number of drugs and their intermediates have been produced by ozonolysis. [ 22 ] The use of ozone in the pharmaceutical industry is difficult to discern owing to confidentiality considerations.
But by tweaking this structure to a PR 3 Ta(CHt−bu)(Ot−bu) 2 Cl (replacing chloride by t-butoxide and a cyclopentadienyl by an organophosphine, metathesis was established with cis-2-pentene. [45] In another development, certain tungsten oxo complexes of the type W(O)(CHt−Bu)(Cl) 2 (PEt) 3 were also found to be effective.
Methylpentene is an alkene with a molecular formula C 6 H 12.The prefix "methyl-" is derived from the fact that there is a methyl(CH 3) branch, the word root "-pent-" is derived from the fact that there are 5 carbon atoms in the parent chain, while the "-ene" suffix denotes that there is a double bond present, as per IUPAC nomenclature.

The oxime first reacts with the ozone to form the corresponding carbonyl oxide, undergoes 1,3-dipolar cycloaddition with the carbonyl reactant to form the cyclic ozonide, as usual for the Criegee intermediate in the ozonolysis of alkenes. If no carbonyl compound is used, the carbonyl oxide may dimerize and form 1,2,4,5-tetraoxanes.
