The structures of the molecules C(SiXMe2)4 (X=H, F, Cl, Br) have been determined by gas electron diffraction (GED). Ab initio calculations revealed nine potential minima for each species, with significant ranges of energies. For the H, F, Cl, and Br

The reactions of [HIr4(CO)9(Ph2PC CPh)(μ-PPh2)] (1) or [Ir4(CO)8(μ3-η2-HCCPh)(μ-PPh2)2] (2) with HC CPh gave two isomeric forms of [Ir4(CO)6(μ3-η2-HCCPh)(μ2-η4-C4H2Ph2)(μ-PPh2)2] (3 and 4) in good yields as the only products. These compounds

Whilst seeking to improve the yield of a Heck-style arylation/fragmentation reaction using a silyloxy substituted meta photocycloadduct, an alternative reaction pathway was discovered that led to the formation of the unique oxidatively cyclised compo

The vinylogous thiazine urethanes 1 are invariably acylated on carbon and not on nitrogen, even when the carbon is “blocked” as in 18. The analogous thiazolidine 2 is acylated either on carbon or nitrogen, depending on the electrophile used.

Multinuclear NMR spectroscopy and X-ray diffraction techniques have been used to identify diastereomeric mixtures of rac- and meso-di(phosphaguanidine) compounds. A brief survey of their coordination chemistry has demonstrated the formation of N,N'-b

Substituted benzene derived meta photocycloadducts have been shown to undergo a fragmentation/arylation reaction under Heck reaction conditions to give bridged bicyclo[3.2.1] compounds in a highly atom-efficient manner. When an anisole derived meta p

A series of heteroleptic calcium eta(5)-C5R5 cyclopentadienides supported by an N-Dipp (Dipp = 2,6-(Pr2C6H3)-Pr-i)-substituted beta-diketiminate ligand have been synthesised by selective protonolysis of the readily available reagent [HC{(C(Me)N(Dipp)

Reactions between sodium amides Na[N(SiMe3)R1] [R1 = SiMe3 (1), SiMe2Ph (2) or But (3)] and cyanoalkanes RCN (R = Ad or But) were investigated. In each case the nitrile adduct [Na{mu-N(SiMe3)2}(NCR)]2 [R = Ad (1a) or But (1b)], trans-[Na{mu-N(SiMe3)(

The "selective" protonolysis of the beta-diketiminato calcium derivative [Ca{(NDippCMe)(2)CH}{N(Si-Me-3)(2)}(THF)] (Dipp = (C6H3Pr2)-Pr-i-2,6) with a selection of terminal alkynes has produced a series of dimeric acetylides [Ca{(NDippCMe)(2)CH}{mu-C
