[1] To the east, the Bucegi Mountains have a very steep slope towards the popular tourist destinations in the Prahova Valley, such as Bușteni and Sinaia. At a higher elevation is the Bucegi Plateau, where wind and rain have turned the rocks into spectacular figures such as the Sphinx and Babele.
The A2 motorway (Romanian: Autostrada A2), also known as The Motorway of the Sun (Romanian: Autostrada Soarelui), is a motorway in Romania which links Bucharest with Constanța, a city-port on the shore of the Black Sea, where it merges after an interchange into the A4 motorway. [3] It is 206 km long, [1] [2] and has been operational on its ...
1,5-Hexadiene is produced commercially by the ethenolysis of 1,5-cyclooctadiene: [1] (CH 2 CH=CHCH 2) 2 + 2 CH 2 =CH 2 → 2 (CH 2) 2 CH=CH 2. The catalyst is derived from Re 2 O 7 on alumina. A laboratory-scale preparation involves reductive coupling of allyl chloride using magnesium: [2] 2 ClCH 2 CH=CH 2 + Mg → (CH 2) 2 (CH=CH 2) 2 + MgCl 2
The A7 motorway (Romanian: Autostrada A7), [1] also known as the Ploiești–Siret Motorway (Romanian: Autostrada Ploiești–Siret) or the Moldavia Motorway (Romanian: Autostrada Moldovei), [2] is a partially built motorway in Romania, that upon completion will link Ploiești to the north-eastern part of the country, partly along the Pan-European Corridor IX.
2,3-pentadiene, H 3 C−CH=C=CH−CH 3, with two enantiomers (R and S). [5] It and 1,2-pentadiene are the least common isomers of pentadiene. Well known derivatives containing pentadiene groups include hexadienes , cyclopentadiene , and especially three fatty acids linoleic acid , α- linolenic acid , and arachidonic acid as well as their ...
Compared with its isomer cyclohexa-1,4-diene, cyclohexa-1,3-diene is about 1.6 kJ/mol more stable. [5] Cyclohexadiene and its derivatives form (diene)iron tricarbonyl complexes. Illustrative is [(C 6 H 8)Fe(CO) 3], an orange liquid. This complex reacts with hydride-abstracting reagents to give the cyclohexadienyl derivative [(C 6 H 7)Fe(CO) 3 ...
The Bucegi Natural Park with an area of 32.663 ha [3] was declared a protected area by Law Number 5 of March 6, 2000 (published in Monitorul Oficial Number 152 of April 12, 2000) [4] and represents a mountainous area (caves, pit caves, canyons, ridges, sinkholes, valleys, waterfalls, pastures and forests), that shelters a variety of flora and fauna.
