CHLORO(1,5-CYCLOOCTADIENE)(PENTAMETHYLCYCLOPENTADIENYL)RUTHENIUM (II)

Reactions

1. Catalyst for regio and stereo-specific ring opening via N-O bond cleavage.
2. Catalyst for transformation of 1,6-enynes and diazoalkanes into alkenylbicyclo[3.1.0]hexane derivatives.
3. Catalyst for ring closing enyne metathesis.
4. Catalyst for [2 + 2 + 2] cocyclization of diene-yne, and cyclodimerization of allenynes.
5. Catalyst for hydrovinylation of ynamides with ethylene.
6. Catalyst for C–H insertion reactions of carbenes. 

Uses

• To catalyze cyclotrimerization of alkynylboronates, propargyl alcohols, and terminal alkynes to form arylboronate, which in turn undergoes palladium(II)-catalyzed carbonylation to form highly substituted phthalides.
• To catalyze C-C coupling of norbornenes and norbornadiene with alkynes?to form [2 + 2] cycloadducts.
• In combination with 2-diphenylphosphinoethylamine-potassium tertiary butoxide to form a ternary catalyst system that can catalyze fast racemization of chiral non-racemic sec-alcohols.
• To synthesize new organoruthenium complexes with phosphorus-based ligands such as bis(phosphino)amines.
• To catalyze the addition of organic disulfides to alkenes leading to vic-dithioethers.
