A compound of the formula: wherein R1 is H or a substituent; m is 1-3; Ar is an aromatic group which may be substituted; X is a bond or a divalent straight-chain group having 1-6 atoms which may be substituted; Y is —S—, —O—, or —N(R2— (R2 is H or a substituent group), Z is —N= or —C(R3)= (R3 is H or a hydrocarbon group), ring A is a benzene ring; ring B is a 5- to 7-membered ring which may be substituted, or a salt thereof is useful for eliciting a prostaglandin I2 receptor agonistic effect.

A series of α-substituted benzylphosphonic acids is described as inhibitors of human prostatic acid phosphatase, an enzyme has been used as a model to study aryl phosphatases. The most potent inhibitors in this series are 2-trifluoromethylbenzhydrylphosphonic acid (9 μM), and α-(2-phenylethyl)benzylphosphonic acid (14 μM). The structure-activity studies suggest that bulk tolerance beyond the phosphate binding area limits the steric or hydrophobic contribution to inhibitor potency achieved through α-carbon substitution.

Solvolyses of monosubstituted benzhydryl bromides gave excellent linear correlations of logk with ?(1+) constants, and not with Y(BnBr) or Y(Br).Correlation analyses against corresponding logk of α-tert-butyl-(2-naphthyl)methyl bromide provided evidence for the importance of different extent of solvation in delocalized transition state and for nucleophilic solvent intervention in the solvolysis of benzhydryl systems.
