Toluenesulfinate serves as a cocatalyst for the selective formation of α-hydroxy α-octa-2,7-dienyl ketones (2, the products of C-C bond formation) in the reaction of palladium catalyzed dimerization of 1,3-butadiene with acyloins, while the same reaction using triphenylphosphine, instead of toluenesulfinate, as a cocatalyst provides a mixture of 2 and 2-oxy octa-2′,7′-dienyl ethers (3, the products
甲苯亚用作α羟基α - 辛-2,7-二烯基酮的1,3-丁二烯与偶姻的钯催化的二聚化反应的选择性形成(2,CC键形成的产物)的助催化剂,而在相同的反应中,使用三苯膦代替甲苯磺酸盐作为助催化剂,可提供2和2-氧八烷-2',7'-二烯基醚的混合物(3,CO键形成的产物)。
