Are there alternatives to cycloocta-1,5-diene;dichlororuthenium (CAS: 50982-12-2) in synthesis?

While cycloocta-1,5-diene;dichlororuthenium (CAS: 50982-12-2) is a highly effective catalyst in certain reactions, there are several alternatives that can be used in synthesis. For instance, ruthenium complexes such as [Ru(bpy)3]2+ (tris(bipyridine)ruthenium(II)) are often used as alternative catalysts in homogeneous catalysis. Other alternatives include palladium-based catalysts and transition metal complexes that can achieve similar catalytic effects under different reaction conditions.
