ABSTRACT:
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
