Next, we aimed to demonstrate the synthetic utility of these phosphonium salt products (11) through a selective reduction of the C-+ P bonds, affording the important (unsymmetrical) diarylmethane scaffolds 12. In this regard, a hydrolysis-based reduction protocol has been developed for benzhydryl triarylphosphonium salts 11 using H2O (Figure ). In this method, we explored the reduction of a benzhydryl triarylphosphonium salt, specifically utilizing 11t as a standard salt for reaction optimization. Various organic and inorganic bases were employed for the reaction, and the supporting information provides further details on these bases (See SI pages xx-xx). Ultimately, KOH was identified as the optimal base for the hydrolytic reduction of the benzhydryl triarylphosphonium salt, leading to the formation of diarylmethane 12i with an isolated yield of 87% (Figure ). 1 . Subsequently, we successfully synthesized a variety of unsymmetrical diarylmethane derivatives 12aad by adapting the standard reaction conditions outlined in Figure . The reaction exhibited a broad scope, encompassing aryls with substituents such as -OMe, -CH2OH, -F, -Cl, -Br, -Ph, -NO2, -CF3, penta-flouro, and -Me, with good yields. Notably, even benzhydryl triarylphosphonium salts containing heteroarenes, such as furan and indoles yielded the desired diarylmethan derivatives (12waa, respectively) with good yields.
