在紫外线的作用下,四甲基双膦容易与烯烃(C 2 H 4,CH 2:CF 2,CH 2:CHF,C 3 H 6)反应,生成相应的1,2-双(二甲基膦基)乙烷在黑暗中不会在100°下反应。当用烯烃(C 2 H 4,C 2 F 4,C 3 H 6,顺式和反式-MeCH:CHMe,CH 2:CHF,CH 2:CF 2),并且在50°C且没有光照的情况下,虽然速度要慢得多。四甲基二膦二硫化物在与氟代烯烃(CH 2:CF 2,CH 2:CHF)一起加热时仅产生分解产物。

An hepatobiliary imaging agent is disclosed which is a cationic complex ofTc-99m, a cyanateorthiocyanate ion, and a mono or polydentate organic ligand having one or more donor atoms, each with a free-electron pair available for accepting a proton or for complexing with Tc-99m to form a cationic complex. These complexes can provide images of the hepatobiliary transit in as little as ten minutes.
