  The presence of defects can introduce important changes in the electronic
structure of graphene, leading to phenomena such as C magnetism. In addition,
vacancies are reactive and permit the incorporation of dopants. This paper
discusses the electronic properties of defective graphene for O and B
decoration. Phonon calculations allow us to address directly the stability of
the systems under study. We show that it is possible to obtain magnetic
solutions with and without dangling bonds, demonstrating that C magnetism can
be achieved in the presence of B and O.
