In the title compound, C16H17ClO, the cyclo-hexene ring adopts a half-chair conformation and the best plane through the six ring atoms makes a dihedral angle of 6.69 (7)° with the chlorophenyl ring. In the crystal, pairs of C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R 2 (2)(20) dimers. The dimers are linked into an infinite chains along the b-axis direction by further C-H⋯O h...

The asymmetric unit of the title compound, C(14)H(16)ClNO, contains two independent mol-ecules, both with the cyclo-hexene ring in a sofa conformation. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules related by translation along the a axis into two crystallographically independent chains. Weak C-H⋯π inter-actions are also observed.

To explore the possibility of producing a narrow distribution of mid- to long-chain hydrocarbons from ethylene as a chemical feedstock, co-oligomerization of ethylene and linear α-olefins (LAOs) was investigated, using a previously reported chromium complex, [CrCl(3)(PNP(OMe))] (1, where PNP(OMe) = N,N-bis(bis(o-methoxyphenyl)phosphino)methylamine). Activation of 1 by treatment with modified me...

Crossed molecular beams experiments have been utilized to investigate the reaction dynamics between two closed shell species, i.e. the reactions of tricarbon molecules, C3(X Sg ), with allene (H2CCCH2; X A1), and with methylacetylene (CH3CCH; X A1). Our investigations indicated that both these reactions featured characteristic threshold energies of 40–50 kJ mol . The reaction dynamics are indir...

The title compound, C(11)H(10)O(2), crystallizes with two independent mol-ecules in the asymmetric unit. In one mol-ecule, the dihedral angle between the mean planes of the C-C=C-C group of the diene unit and essentially planar cyclo-hexene ring is 51.07 (9)°, while in the other mol-ecule it is 54.49 (12)°. In the crystal structure, weak inter-molecular C-H⋯O inter-actions link the mol-ecules i...

Catalytic dehydrocoupling of primary and secondary phosphines has been achieved for the first time using an iron pre-catalyst. The reaction proceeds under mild reaction conditions and is successful with a range of diarylphosphines. A proton acceptor is not needed for the transformation to take place, but addition of 1-hexene does allow for turnover at 50 °C. The catalytic system developed also ...

In the title mol-ecule, C(14)H(16)O, the cyclo-hexene ring adopts an envelope conformation, with all substituents equatorial. Mol-ecules are linked by C-H⋯O hydrogen bonds. A C-H⋯π inter-action involving the benzene ring is also found in the crystal structure. The H atoms of both methyl groups are disordered equally over two positions.
