The Michaelis–Arbuzov reactions of benzylselenocyanate and 5′-deoxythymidine-5′-selenocyanate with thymidine H-phosphonate proceeded rapidly in the presence of a neutral silylating agent and 2,6-lutidine to give the corresponding Se-alkyl phosphoroselenolate triesters. Deprotection under mild conditions enabled the isolation of phosphoroselenolate diesters which were fully characterised.
在中性甲硅烷基化剂和2,6-二甲基吡啶的存在下,苄基硒氰酸酯和5'-脱氧胸苷-5'-硒氰酸酯与胸苷H-膦酸酯的Michaelis-Arbuzov反应迅速进行,得到相应的Se-烷基磷酸亚硒酸酯三酯。在温和的条件下脱保护使得能够分离出特征充分的亚油酸酯磷酸二酯。
