General tips：For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging：1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition：Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Density functional theory study of Rh(III)-catalyzed C-H activations and intermolecular annulations between benzamide derivatives and allenes.[Pubmed:25856513]

Inorg Chem. 2015 Apr 20;54(8):3958-69.

Density functional theory has been applied to gain insight into the Cp*Rh(OAc)2-catalyzed C-H activation and intermolecular annulation of Benzamide derivatives with allenes. The study shows that the reactions proceed in three steps: (1) C-H activation induced by Rh catalyst reacting with Benzamide derivatives, (2) carborhodation of allene, and (3) regeneration of Rh catalyst. The results indicate that the N-H deprotonation makes the following C-H activation much easier. The regio- and stereoselectivities of 1a (N-pivaloyloxy Benzamide)/2a (cyclohexylallene) and 1b (N-pivaloyloxy-4-methyl-Benzamide)/2b (1,1-dimethyl allene) depend on the allene carborhodation step. The steric hindrance effect is the dominant factor. We also discuss the reaction mechanism of 1c (N-methoxy Benzamide)/2a. The chemoselectivity between 1c/2a is determined by the N-O cleavage step. Replacement of OPiv by OMe leads to loss of the stabilization effect provided by C=O in OPiv. Additionally, Cp*Rh(OAc)(OPiv) is produced in the Cp*Rh(OAc)2 regeneration step, which can work as catalyst as well.
