Abstract
The reaction of [Pt(η-C2H4)(PPh3)2] with CHRXY (CH2I2, CH2Br2, CH2BrCl, CH2BrI, CH2ClI, or CHBr3) affords trans-(and usually also cis-)[Pt(CHRX)-(PPh3)2Y], whereas [Pt(PEt3)3] and CH2I2 yield trans-[Pt(CH2PEt3)I(PEt3)2]I; X-ray analysis of the title compound to R 0·064 shows Pt–P (trans to I) 2·228(6), Pt–P (trans to CH2I) 2·355(7), Pt–C 2·08(2), and Pt–I 2·658(3)Å, ∠PPtP 97·1(2), and ∠CPtI 83·3(5)°.Keywords
