We consider an exact solvable interacting spinful Kitaev chain which is a generalization of the Mattis-Nam model. A nearest-neighbor dimerized interaction favoring the production of disjoint molecules drives the quantum phase into an insulating one. The phases are characterized statically and dynamically in terms of magnetization and spin-singlet correlations by using the exact solution. The model is shown to be exactly solvable also in the presence of boundary interactions which are originated from a spin-singlet superconducting pairing and a magnetic field. We exploit the exact solution to investigate the out-of-equilibrium dynamics as due to a quench at the boundary. The propagation of the disturbance in nearest-neighbor magnetic and spin-singlet pairing displays a ballistic behavior for long times with different velocities.
