An important synthetic application using such dialkylboranes, such as diethylborane, is the transmetallation of the organoboron compounds to form organozinc compounds. [9] [10] Some diaryl and dialkylboranes are well known. Dimesitylborane is a dimer (C 6 H 2 Me 3) 4 B 2 H 2). It reacts only slowly with simple terminal alkenes.
A borate is any of a range of boron oxyanions, ... like K 2 Al 2 B 2 O 7 and Cs 3 Zn 6 B 9 O 21 have been considered for applications in nonlinear optics. [8] Borate ...
At the age of 21, he left Wisconsin to prospect for mineral wealth in the American West, starting in Nevada. [4]In 1872, while contracting to provide firewood to a small borax operation at nearby Columbus Marsh, Smith discovered a rich supply of ulexite at Teels Marsh in Mineral County, Nevada, east of Mono Lake, near the town he would found ten years later, Marietta, Nevada, while looking ...
When the Storey brothers' interests were subsequently acquired in 1873, the name was shortened to Smith Brothers Borax Co. A few years later (circa 1884) it was changed again to Teel's Marsh Borax Co. In 1880, the separate and previously existing Pacific Borax Company (with no "Coast" in the name) was acquired by Smith. Frank Smith also ...
Many sodium borates have important industrial and household applications; the best known being borax, (Na +) 2 [B 4 O 5 (OH) 4] 2− ·8H 2 O = Na 2 B 4 H 20 O 17. The ternary phase diagram of the Na 2 O – B 2 O 3 – H 2 O phase diagram in the 0–100 °C temperature range contains 13 unique hydrated crystalline sodium borates, including ...
Twenty-mule-team wagons on display in Death Valley, California The vehicles The carriage assembly. In 1877, six years before twenty-mule teams would be introduced in Death Valley, Scientific American reported that Francis Marion Smith and his brother had shipped their company's borax in a 30-ton load using two large wagons, with a third wagon for food and water, drawn by a 24-mule team over a ...
Trimethyl borate is the organoboron compound with the formula B(OCH 3) 3 and a metal alkoxide. It is a colourless liquid that burns with a green flame. [1] It is an intermediate in the preparation of sodium borohydride and is a popular reagent in organic chemistry. It is a weak Lewis acid (AN = 23, Gutmann-Beckett method). [2]
The tetrapropylboranuide anion is a reagent for the propylation of organometallic compounds, including organotin, organomercury, and organolead compounds of interest to environmental and public health research. [4]
