When is an Imine Directing Group a Transient Imine Directing Group in C−H Functionalization?
Chemistry - A European Journal‘Transient’ C–H functionalization has emerged in recent years to describe the use of a dynamic linkage, often an imine, to direct cyclometallation and subsequent functionalization.

On the Group of a Directed Graph
Canadian Journal of Mathematics, 1966In 1938, Frucht (2) proved that for any given finite group G there exists a finite symmetric graph X such that G(X) is abstractly isomorphic to G. Since G(X) is a permutation group, it is natural to ask the following related question : If P is a given finite permutation group, does there exist a symmetric (and more generally a directed) graph X such ...

On Direct Products of Abelian Groups
Canadian Journal of Mathematics, 1970In this paper we investigate the properties of the product (or complete direct sum) of torsion Abelian groups. The chief results concern products of Abelian primary groups (p-groups). Given a set of p-groups, [Gλ], over an index set Λ, the product of these groups is written λλ∈ΔGλ, the torsion subgroup of the product of these p-groups is written T[λGλ],

Direct Cancellation of Finite Groups
Algebra Colloquium, 2005We prove that if F is a finite group, and G and H are finitely generated groups with finite commutator subgroups for which F × G ≃ F × H, then G ≃ H.

On the Automorphism Group of Direct Products of Groups with Finite Exponent
The American Mathematical Monthly, 2021We study the direct product of the automorphism groups of a finite number of groups. This is always isomorphic to a subgroup of the automorphism group of the direct product of the initial groups an...

TEST ELEMENTS IN DIRECT PRODUCTS OF GROUPS
International Journal of Algebra and Computation, 2000We characterize test elements in the commutator subgroup of a direct product of certain groups in terms of test elements of the factors. This provides explicit examples of test elements in direct products whose factors are free groups or surface groups and a tool for doing the same for torsion free hyperbolic factors.
