The dinuclear system approach, coupled with the statistical decay model GEMINI++, was used to investigate multinucleon transfer reactions. Experimental production cross-sections in the reaction \(^{129}\) Xe+ \(^{248}\) Cm were reproduced to assess the reliability of these theoretical models. The production of neutron-deficient transcalifornium nuclei with \(Z = 99-106\) was examined in multinucleon transfer reactions, including \(^{124}\) Xe + \(^{248}\) Cm, \(^{124}\) Xe + \(^{249}\) Cf, and \(^{129}\) Xe+ \(^{249}\) Cf. Both the driving potential and the neutron-to-proton equilibration ratio were found to dominate the nucleon transfer process. The reaction \(^{124}\) Xe + \(^{249}\) Cf is proposed as a promising projectile-target combination for producing neutron-deficient isotopes with \(Z = 99-106\) , with the optimal incident energy identified as \(E_{\text {c. m.}} = 533.64\) MeV. Production cross-sections of 25 unknown neutron-deficient trancalifornium isotopes with cross-sections greater than 1 pb were predicted.
