An incommensurate thiourea inclusion compound.
X-Ray diffraction studies reveal that the tunnel inclusion compound formed between 1-tert-butyl-4-iodobenzene and thiourea has an incommensurate relationship between the periodicities of the host and guest substructures along the tunnel axis, representing the first reported case of an incommensurate thiourea inclusion compound.
متن کاملFeeding of the Bee Families with an Addition of CoSO4
For their normal living, honey bees (Apis mellifera) require proteins, carbohydrates, lipids, vitamins and minerals. It is well known that Co and vitamin B12 are two nutrients that have been reported in pollen and plants that have had positive results in bees feeding. In this respect, the aim of the study is to determine the influence of feeding of the bee families with CoSO4 as a supplement on...
متن کاملSHORT COMMUNICATION Pharmacokinetic Studies of the Fragrance Compound 1f8-Cineol in Humans during Inhalation
The present study was undertaken to investigate the pharmacokinetics of 1,8-cineol in human subjects during prolonged inhalation. The results showed that 1,8-cineol is well absorbed from breathing air, with a peak plasma concentration after -18 min. The elimination of this fragrance compound from the blood is biphasic, with a mean distribution half-life of 6.7 min and an elimination half-life o...
متن کاملEfficient synthesis of optically active 4-nitro-cyclohexanones via bifunctional thiourea-base catalyzed double-Michael addition of nitromethane to dienones.
Thiourea-modified cinchona alkaloids as bifunctional catalysts and a base could catalyze a stepwise [5+1] cyclization of divinyl ketones with nitromethane via double Michael additions, furnishing optically active 4-nitro-cyclohexanones with good yields, excellent diastereoselectivities (>20 : 1) and high enantiomeric ratios (up to 97 : 3).
