Reactions of Cl2P(CH2)3PCl2andp-MgBrC6H4X (X =a/OMe,b/OtBu,c/tBu,d/SiMe3) give the diphosphines (p-XC6H4)2P(CH2)3P(p-C6H4X)2(1a–d; 47–66%). Additions of1a,dto (COD)PtCl2yield (CH2(CH2P(p-C6H4X)2)2)PtCl2(2a,d; 62–88%), which upon reaction with butadiyne (2 equiv; HNEt2/cat. CuI) give (CH2(CH2P(p-C6H4X)2)2)Pt((C≡C)2H)2(3a,d; 34–76%). Alternatively,3a–dcan be accessed fromtrans-(p-tol3P)2Pt((C≡C)2H)2and1a–d(30–87%). Reactions of (p-tol3P)2PtCl2and H(C≡C)2SiR3(2 equiv, HNEt2/cat. CuI; R = Me/Et/iPr) givetrans-(p-tol3P)2Pt((C≡C)2SiR3)2(77–95%), and subsequent additions of1a,b,dyield the corresponding adducts (CH2(CH2P(p-C6H4X)2)2)Pt((C≡C)2SiR3)2(R/X = Me/OMe,5a;iPr/OMe,6a;iPr/OtBu,6b;iPr/SiMe3,6d; 52–95%) and (for5a) a luminescent diplatinum byproduct withtransPt((C≡C)2SiMe3)2units.5aand6bhydrolyze in the presence of F–to3a,b(92–93%). Reaction of2aand3a(HNEt2/cat. CuI) affords the Pt4C16polygon ([(CH2(CH2P(p-C6H4OMe)2)2)Pt(C≡C)2]4as an H2NEt2+Cl–adduct (66%). The13C{1H} NMR spectra of3a–d,5a, and6a,b,dfeature complex AMXX′ (CPtPP′) spin systems, and simulations allowJvalues to be extracted. The crystal structures of2a,3a,b,d,5a, and6aare determined and analyzed.
