R2=(Me3Si)2CH, R1=Ph, (L)n=tmeda (3Pb); R2=Ph, R1=Me, (L)n=(THF)1.33 (5Pa); R2=Ph, R1=Me, (L)n=([12]crown‐4)2 (5Pc)]. Treatment of 1PH with either PhCH2Na or PhCH2K yields the heavier alkali metal complexes [(Me3Si)2CH}P(C6H4‐2‐SMe)]M(THF)n [M=Na (1Pd), K (1Pe)]. With the exception of 2Pa and 2Pb, photolysis of these complexes with white light proceeds rapidly to give the thiolate species [R2P(R1)(C6H4‐2‐S)]M(L)n
