Investigation of electronic communication and guest inclusion using photoluminescent macrocyclic receptors with Ru(II) centers and Ph2P-C≡C- C≡C-PPh2 spacers

An enhanced photoluminescence is observed upon addition of organic guests to the trimeric macrocycle (see picture; tpy = 2,2':6',2''- terpyridine). The use of a short alkyne bridge has enabled the rigid trimer and the smaller dimer to be prepared with controllable cavity sizes. A better redox communication between the Ru centers in the dimer is also observed.

( Z)-1-Methoxy-4-( diphenylphosphino) but-1-ene-3-yne: A versatile synthon for unsymmetrically substituted ( diphenylphosphino) diacetylene derivatives

An efficient synthesis of Ph2P-C≡C-C≡C-Li, 1, was found, starting from commercially available (Z)-1-methoxybut-1-ene-3-yne and its diphenylphosphino derivative 2. The lithio compound 1 was condensed with electrophiles to give Ph2P-C≡

Some Transition Metal Complexes of the Diacetylenic Diphosphine Ph2PC2C2PPh2: Synthesis and Crystal Structures

Several complexes of the acetylenic ditertiary phosphine, Ph2PC2C2PPh2, containing Mo, W, Fe, Ru or Au have been prepared; one CC triple bond in the Mo, W or Fe derivatives has been co-ordinated to Co2(CO)6 or Pt(PPh3)2 groups.Crystal structure determinations of 2(μ-PPh2C2C2PPh2)> 3 and 2-CC>(CO)6> 7 show that the P-bonded M(CO)n groups take up transoid positions; in 3, the PCCCCP chain, which is situated about a centre of inversion, is nearly linear with CC distances of 1.192(7) Angstroem .In 7, co-ordination of the Co2(CO)6 group to one CC bond lengthens that bond by 0.13 Angstroem, compared with the unco-ordinated CC bond, and induces bend-back of the substituents of 141-143(1) deg (PPh2) and 145-146(1) deg (C2PPh2).Crystals of 3 are triclinic, space group P1/, a = 11.261(1), b = 12.456(2), c = 13.061(2) Angstroem, α = 79.23(2), β = 75.73(1), γ = 78.75(2) deg, Z = 2; 2870 data were refined to R = 0.042, R'= 0.046.Crystals of 7 are triclinic, space group P1/, a = 17.940(4), b = 19.695(4), c = 16.449(2) Angstroem, α = 111.92(1), β = 108.83(1), γ = 100.29(2) deg, Z = 4; 5942 data were refined to R = 0.055, R'= 0.056.
