Abstract
The synthesis of the 1st generation dendrimer 1,3,5-{trans-[Ru(C≡C-3,5-(trans-[Ru(C≡CPh)(dppe)2(C≡CC6H4-4-(E)-CH[DOUBLE BOND]CH)])2C6H3)(dppe)2(C≡CC6H4-4-(E)-CH[DOUBLE BOND]CH)]}3C6H3 proceeds by a novel route that features Emmons-Horner-Wadsworth coupling of 1,3,5-C6H3(CH2PO(OEt)2)3 with trans-[Ru(C≡CC6H4-4-CHO)Cl(dppe)2] and 1-I-C6H3-3,5-(CH2PO(OEt)2)2 with trans-[Ru(C≡CPh)(C≡CC6H4-4-CHO)(dppe)2] as key steps. The stilbenylethynylruthenium dendrimer is much more soluble than its ethynylated analog 1,3,5-{trans-[Ru(C≡C-3,5-(trans-[Ru(C≡CPh)(dppe)2(C≡CC6H4-4-C≡C)])2C6H3)(dppe)2(C≡CC6H4-4-C≡C)]}3C6H3 and, in contrast to the ethynylated analog, is a two-photon absorber at telecommunications wavelengths.
