Organogermanium compounds having both hydrophilicity and lipophilicity are respresented by the formula ##STR1## in which R.sub.1 and R.sub.2 are each a hydrogen atom or a lower alkyl group, and A is a hydroxyl or amino group, a salt thereof, or an O-lower alkyl group. The compounds are produced by a process which comprises obtaining a trihalogermylcinnamic acid derivative of the formula ##STR2## in which R.sub.1 and R.sub.2 are each a hydrogen atom or a lower alkyl group, and B is a cyano, carboxyl, haloformyl, or carbamoyl group, or a group esterified with a lower alkyl group, directly or indirectly from a cinnamic acid derivative of the formula ##STR3## in which R.sub.1, R.sub.2, and B are as defined above, and a trihalogermane X.sub.3 GeH (III) and then hydrolyzing the derivative (IV).
具有亲水性和亲脂性的有机锗化合物的化学式为##STR1##其中R.sub.1和R.sub.2分别是氢原子或较低的烷基,A是羟基或氨基,其盐或O-较低烷基基团。该化合物的制备方法包括从具有以下化学式的肉桂酸衍生物中直接或间接获得以下化学式的三卤代基肉桂酸衍生物##STR2##其中R.sub.1和R.sub.2分别是氢原子或较低的烷基,B是氰基,羧基,卤代甲酰基或氨甲酰基或酯化有较低烷基基团的基团。然后,将三卤代锗烷X.sub.3 GeH (III)和衍生物(IV)水解即可制备该化合物。
