A G–ring is any commutative ring R with a nonzero identity such that the total quotient ring \(\mathbf {T}(R)\) is finitely generated as a ring over R. A G–ring pair is an extension of commutative rings \(A\hookrightarrow B\), such that any intermediate ring \(A\subseteq R\subseteq B\) is a G–ring. In this paper we investigate the transfer of the G–ring property among pairs of rings sharing an ideal. Our main result is a generalization of a theorem of David Dobbs about G–pairs to rings with zero divisors.
