The synthesis of thirteen new compounds α - [2 - (2, 4 -dichlorophenoxy) propionyloxy] alkyl phosphonates was described. The structures of these compounds were characterized by IR, 1H-NMR and MS.
A series of polydimethylsiloxanes containing two primary hydroxyl groups at one single chain end were synthesized by five-step reactions which included esterification,hydroxyl protection,anionic ring-opening polymeriz...A series of polydimethylsiloxanes containing two primary hydroxyl groups at one single chain end were synthesized by five-step reactions which included esterification,hydroxyl protection,anionic ring-opening polymerization,hydrosilylation and deprotection.The prepared compounds in each step were characterized.The results showed that each step synthesis was successfully carded out and objective products could be achieved.展开更多
