50982-12-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact.50982-12-2, Dichloro(cycloocta-1,5-diene)ruthenium(II) it is a common compound, a new synthetic route is introduced below.

A mixture of [RuCl2(COD)]n (309 mg, 1.103 mmol), PCy3 (309 mg, 1.103 mmol) and la (294 mg, 1.103 mmol) was stirred in toluene (10 ml) at 115 C for 48 h in a KONTES pressure tube. After cooling down, the brick colored precipitate was collected on a filter frit, washed with Et20 (3 x 10 ml) and vacuum dried to afford 642 mg of the crude material. To the crude material was added CH2C12 (~ 32 ml) and the obtained mixture was brought to reflux and filtered using a Whatman syringe filter (PTFE membrane, pore size 0.45 muiotaeta). Layering the obtained red-brown solution with Et20 (125 ml) afforded 327 mg (41%) of the product as a pink-brown powder after 5 days. Elem.
