Phenyl N-(p-tolyl)carbamate
The asymmetric unit of the title compound, C(14)H(13)NO(2), contains two crystallographically independent mol-ecules, in which the aromatic rings are oriented at dihedral angles of 59.01 (3) and 56.98 (3)°. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains.

In the title compound, C(15)H(17)NO(2)S, the aromatic rings are oriented at a dihedral angle of 32.8 (1)°. The ethyl group and phenyl ring on the N atom adopt a staggered conformation with respect to the O atoms.
متن کاملAlternating copolymerization of limonene oxide and carbon dioxide.
The alternating copolymerization of (R)- or (S)-limonene oxide and CO2 using beta-diiminate zinc acetate catalysts is reported. At 100 psi CO2 and 25 degrees C, the catalyst exhibits a high selectivity for the trans isomer and produces regioregular polycarbonate. The copolymer contains >99% carbonate linkages, a narrow molecular weight distribution, and an Mn value consistent with the [epoxide]...
متن کاملN-Phenyl-2-p-tolylthiazole-4-carboxamide derivatives: Syn-thesis and cytotoxicity evaluation as anticancer agents
Objective(s):According to the prevalence of neoplastic diseases, there is a deep necessity for discovery of novel anticancer drugs in the field of medicinal chemistry. In the current study, a new series ofphenylthiazole derivatives(compounds 4a-4f) was synthesizedand theiranticancer activity was assessed in vitro. Materials and Methods:All synthesized derivatives were evaluated towards three h...
متن کاملMechanistic studies of CO2 reduction to methanol mediated by an N-heterocyclic germylene hydride.
The labile germylene hydride L(Cy)GeH is capable of activating CO2 affording the corresponding formate L(Cy)GeOCH([double bond, length as m-dash]O) (2) (L(Cy) = cyclo-C6H8-1-NAr-2-C(Ph)NAr, Ar = 2,6-iPr2C6H3). Compound and the previously reported LGeOCH([double bond, length as m-dash]O) (L = CH(MeC[double bond, length as m-dash]NAr)2, Ar = 2,6-iPr2C6H3) (2) could be further converted to methano...
