Phenyl Morpholine

Can the bond between Morpholine and Benzene be broken and hence morpholine nitrosated to N-nitroso Morpholine?

I believe that the answer in this case is, in case of doubt, do a Nitrosation assay.
In my opinion, the risks comes more from phenylmorpholine containing certain amounts of morpholine as impurity which can be nitrosated rather than direct nitrosation of phenylmorpholine

Is it possible for the morpholine ring to open? if yes which bond will be more susceptible to break?

Thank you!

we need @conudel to answer the organic chemistry here!! thanks Raphy

Could happen, but it is unlikely, since 6-member rings are quite stable. You would require very harsh reaction conditions to be able to open a morpholine ring. I would not worry about it too much unless mentioned harsh conditions are used
