Co-author refuses to share final manuscript or list of submissions
Yes, your advisor behaviour is unprofessional and certainly against the ethical policies of virtually any serious publisher. I'd contact the other coauthor and write a joint email along the following lines (modify according to your knowledge of the situation):


  Dear X, 
  
  We are disappointed by your refusal to share the final versions of the
  manuscripts and the journals which they have been submitted to. Journal policies require all authors to approve a submission, and not
  only does your refusal go against such policies but it also undermines
  the trust that should exist among coauthors. 
  
  We kindly ask you to comply with our request. In case, we will take
  all the necessary steps to exercise our author's rights.
  
  Best,
  Y and Z


If they still refuse, contact the ethical or disciplinary office of their university, if there is one, or the Head of Department.
