With the Renpho AI Smart Bike, you’re definitely getting something that veers more towards that traditional bike look as opposed to rivalling a Peloton or a Wattbike in the design department. Granted, you’re paying a lot less for it, but it’s by no means the sleekest looking setup we’ve had to put to the test. a b Jeffrey Aube & Gregory L. Milligan (1991).

From the home screen, you can see the option to go for a free cycle, view recent training or perform the Cycling Power Test to produce your functional threshold power (or FTP) to better tailor training programs to each user. This is really the whole AI element of the experience here. Lang, S.; Murphy, J. A. (2006). "Azide rearrangements in electron-deficient systems". Chem. Soc.

Half Life

While you can use the bike manually, you’ll get the most out of it when you take advantage of its connected smarts. Once it’s plugged in, you’ll need to use the console up front to pair the bike to the Renpho AI Gym app (Android and iOS) over Bluetooth. Despite some initial connectivity issues, we didn’t have major problems pairing it up with the Android or iOS apps we tested it with. The app experience across those platforms is pretty consistent too, which is good to see. Below the holder is the circular console, which is essentially a round metal button that you can rotate to scroll through different metrics (RPM, power, cadence and calories), and adjust resistance. The scope of this reaction has been extended to reactions of carbonyls with alkyl azides R-N 3. This extension was first reported by J.H. Boyer in 1955 [9] (hence the name Boyer reaction), for example, the reaction of m-nitrobenzaldehyde with β-azido-ethanol: In addition to the power and video courses, you can also make use of the Challenges, which are essentially scenic rides that are definitely best enjoyed on a tablet as opposed to a phone screen.

[5] These are annulation reactions and have some utility in the synthesis of natural products; [6] [10] such as lactams [11] and alkaloids. [12] Intramolecular Schmidt Reaction See also [ edit ] The reaction is closely related to the Curtius rearrangement except that in this reaction the acyl azide is produced by reaction of the carboxylic acid with hydrazoic acid via the protonated carboxylic acid, in a process akin to a Fischer esterification. An alternative, involving the formation of an acylium ion, becomes more important when the reaction takes place in concentrated acid (>90% sulfuric acid). [7] (In the Curtius rearrangement, sodium azide and an acyl chloride are combined to quantitatively generate the acyl azide intermediate, and the rest of the reaction takes place under neutral conditions.)In organic chemistry, the Schmidt reaction is an organic reaction in which an azide reacts with a carbonyl derivative, usually an aldehyde, ketone, or carboxylic acid, under acidic conditions to give an amine or amide, with expulsion of nitrogen. [1] [2] [3] It is named after Karl Friedrich Schmidt (1887–1971), who first reported it in 1924 by successfully converting benzophenone and hydrazoic acid to benzanilide. [4] The intramolecular reaction was not reported until 1991 [5] but has become important in the synthesis of natural products. [6] The reaction is effective with carboxylic acids to give amines (above), and with ketones to give amides (below).
