Ru-2(OAc)(4)Cl与2.2等量的H(2)esp （esp = α, α, α ', α '-四甲基-1,3-苯二丙酸）反应生成可溶于有机介质的新化合物Ru-2(esp)(2)Cl(1)。1是一种活性催化剂，用于在乙腈溶液或纯（无溶剂）条件下由过氧化叔丁基（TBHP）氧化有机硫化物。无溶剂反应显示了三必和必的定量效用，因此对亚砜的形成具有优异的化学选择性。
The reaction of Ru-2(OAc)(4)Cl with 2.2 equiv of H(2)esp (esp = alpha,alpha,alpha',alpha'-tetramethyl-1,3-benzenedipropionate) resulted in a new compound, Ru-2(esp)(2)Cl (1), that is soluble in organic media. 1 is an active catalyst for the oxygenation of organic sulfides by tertbutyl hydroperoxide (TBHP) in both an acetonitrile solution or neat (solvent-free) conditions. Solvent-free reactions display the quantitative utility of TBHP and hence excellent chemical selectivity for sulfoxide formation.
